Public Bucket Jump Scare
What it is
Storage/bucket code or naming suggests public object exposure may exist without proof of private access 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
Make buckets private by default, issue signed URLs server-side, and test anonymous access denial.
- 1Make buckets private unless a public object is intentional.
- 2Issue signed URLs from server code for private objects.
- 3Test anonymous reads and writes before launch.
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.
