Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Session IDs were previously accepted without format validation or ownership verification. Attackers could hijack sessions or execute injection attacks if the session retrieval API does not validate both the session_id format and the client's IP address.
Path Traversal: User-supplied document paths were opened directly using pymupdf.open without canonicalization. This allowed attackers to traverse outside intended boundaries and read arbitrary system files.
