Upload Endpoint Check — Does Your Upload Accept Any File, No Limits?
DevMeth checks the 48 known AI-code failure patterns — not a penetration test or a security guarantee.
What the issue is
An upload endpoint that accepts any file with no type filter or size limit can be abused to push malware, exhaust disk, or overwrite files on your server.
Why AI tools generate it
AI tools scaffold a working upload with no constraints so the feature demonstrably works, leaving out the file-type filter and size cap.
How DevMeth detects it
A code scan checks upload-library calls for a file-type filter and a size limit, flagging any that accept files unconstrained.
Your upload endpoint accepts any file, no limits
WHAT WE FOUND
upload route — no file-type filter or size limit
The fix, in three steps
Add an allowlist of allowed file types and a hard size limit to every upload path, and never trust the client's claimed type. Three steps.
Run a free scan and each finding carries a paste-ready fix prompt you can act on.
