File Upload Roulette
What it is
File upload or storage flows are present without enough visible proof of size, type, malware, or path controls.
This usually appears when file or object workflows are generated before size, type, path, and access boundaries are made explicit.
How to fix it
Add MIME/type validation, size limits, storage isolation, signed URLs, malware scanning hooks, and abuse tests.
- 1Validate MIME type, extension, and size at the server boundary.
- 2Isolate uploaded objects and use signed URLs for access.
- 3Add malware-scanning hooks and abuse-path tests where uploads are accepted.
How VibeAudit checks for this
VibeAudit checks this with Q0_EXTERNAL_SHALLOW observations, SAST_LOCAL_STRUCTURAL route/config evidence, and non-destructive DAST_Q1_ACTIVE probes when authorized. The free tier may show the surface name only, without private evidence or remediation details. Metadata-only surface maps do not create missing-control findings. Unsupported private repositories, authenticated behavior, destructive workflows, account configuration, and business logic remain unverified unless the scan includes matching local, imported, or authorized runtime evidence.
