Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Sandbox Escape / Arbitrary File Write: User-supplied zip archives are extracted without path validation, allowing zip-slip style writes outside the sandbox.

Auth Bypass: Authentication logic was refactored to add authorization, indicating a prior bypass risk on protected routes.

Insecure Direct Object Reference: Sequential submission IDs allowed enumeration and unauthorized access; fixed by using unguessable tokens.
