Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Arbitrary file write via malicious tar archive member paths; fixed by adding path containment checks and filter='data' in a safe extract wrapper.
Local Privilege Escalation / Information Disclosure: Resumable upload state stored in shared predictable /tmp directory with upload URL and blob token; fixed by per-user directory, 0700 permissions, and symlink/owner checks.
Auth Bypass: Anonymous fallback before OAuth credential check allows unauthenticated access; fixed by reordering to check OAuth credentials first.
