🚨 Potential Security Issue: CORS Configuration

File: src/server.ts
Lines: 44-52
Severity: Medium

Problem

The original CORS configuration used origin: "*", which allows requests from any origin. While the updated code introduces an allowedOrigins array, it's crucial to ensure this array is comprehensive and accurately reflects the permitted origins for your application. Failing to do so could leave the application vulnerable to Cross-Origin Request Forgery (CSRF) attacks.

Current Code

app.use(cors({
origin:  "*",
credentials: true
}));

Suggested Fix

const allowedOrigins = ['http://localhost:3000', 'https://example.com']; // Replace with your actual origins
app.use(cors({
origin: (origin, callback) => {
if (allowedOrigins.includes(origin) || !origin) {
callback(null, true);
} else {
callback(new Error('Not allowed by CORS'));
}
},
credentials: true
}));

Why This Fix Works

• It restricts the allowed origins to a predefined list, mitigating the risk of CSRF attacks from unknown or untrusted origins.
• The || !origin part allows requests without an origin (e.g., same-origin requests or requests from certain tools).

Additional Context

• Important: Thoroughly review and update the allowedOrigins array to include all legitimate origins for your application (e.g., production frontend URL, staging URLs, etc.).
• Consider using environment variables to manage the allowedOrigins list, especially for different environments (development, staging, production).
• For production environments, avoid using origin: true as it can expose your application to security vulnerabilities.
