Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Input Validation / Signature Bypass: A separator that overlaps with the base64 alphabet could let an attacker craft a token whose signature section is ambiguous, potentially bypassing verification.
Signature Verification Bypass: Unhandled exceptions during base64 decoding of a signature could lead to incorrect verification outcomes, allowing invalid signatures to be accepted.
Dependency Vulnerability: The urllib3 dependency carried a high-severity vulnerability affecting network operations; the fix was a version bump, indicating the project must track dependency updates to avoid known exploits.
