Security Advisories 🚨

🚨 nuxt vulnerable to Cross-site Scripting in navigateTo if used after SSR

Summary

The navigateTo function attempts to blockthe javascript: protocol, but does not correctly use API's provided by unjs/ufo. This library also contains parsing discrepancies.

Details

The function first tests to see if the specified URL has a protocol. This uses the unjs/ufo package for URL parsing. This function works effectively, and returns true for a javascript: protocol.

After this, the URL is parsed using the parseURL function. This function will refuse to parse poorly formatted URLs. Parsing javascript:alert(1) returns null/"" for all values.

Next, the protocol of the URL is then checked using the isScriptProtocol function. This function simply checks the input against a list of protocols, and does not perform any parsing.

The combination of refusing to parse poorly formatted URLs, and not performing additional parsing means that script checks fail as no protocol can be found. Even if a protocol was identified, whitespace is not stripped in the parseURL implementation, bypassing the isScriptProtocol checks.

Certain special protocols are identified at the top of parseURL. Inserting a newline or tab into this sequence will block the special protocol check, and bypass the latter checks.

PoC

POC - https://stackblitz.com/edit/nuxt-xss-navigateto?file=app.vue

Attempt payload X, then attempt payload Y.

Impact

XSS, access to cookies, make requests on user's behalf.

Recommendations

As always with these bugs, the URL constructor provided by the browser is always the safest method of parsing a URL.

Given the cross-platform requirements of nuxt/ufo a more appropriate solution is to make parsing consistent between functions, and to adapt parsing to be more consistent with the WHATWG URL specification.

Note

I've reported this vulnerability here as it is unclear if this is a bug in ufo or a misuse of the ufo library.

This ONLY has impact after SSR has occured, the javascript: protocol within a location header does not trigger XSS.

🚨 nuxt Code Injection vulnerability

he Nuxt dev server between versions 3.4.0 and 3.4.3 is vulnerable to code injection when it is exposed publicly.

✳️ postcss (8.4.21 → 8.4.40) · Repo · Changelog

Security Advisories 🚨

🚨 PostCSS line return parsing error

An issue was discovered in PostCSS before 8.4.31. It affects linters using PostCSS to parse external Cascading Style Sheets (CSS). There may be \r discrepancies, as demonstrated by @font-face{ font:(\r/*);} in a rule.

This vulnerability affects linters using PostCSS to parse external untrusted CSS. An attacker can prepare CSS in such a way that it will contains parts parsed by PostCSS as a CSS comment. After processing by PostCSS, it will be included in the PostCSS output in CSS nodes (rules, properties) despite being originally included in a comment.
