Source Map Exposure
Source maps help debug minified code but can expose your original source code if publicly accessible.
Why It Matters
Source maps reveal your application's structure, logic, and potentially hardcoded secrets. This helps attackers understand and exploit your code.
How We Check
We check for .map files and sourceMappingURL comments that might expose your source code.
How to Fix
Don't deploy source maps to production. If needed for error tracking, restrict access to authenticated users or specific IPs.
