Insecure file upload (no type validation)
File upload endpoints that don't validate file type and content allow attackers to upload web shells, scripts, or malicious files that can be executed on the server or served to other users.
HOW VIBECHECK DETECTS THIS
vibecheck clones your repository and runs Gitleaks, Semgrep, njsscan, and a suite of custom checks targeting patterns common in AI-generated code. This check is part of the Server-Side category. When a matching pattern is found, Claude triages the finding and produces a plain-English explanation and a concrete fix — no security expertise required.
