Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Attackers can bypass cryptographic token protections by substituting expected encrypted tokens (JWE) with signed-only tokens (JWS) or submitting malformed serialization types. This allows execution-context impersonation when explicit token type verification is missing.
Cryptographic Issues: The use of deprecated, weak, or timing-vulnerable algorithms (such as RSA-PKCS#1 v1.5) by default can expose encrypted payloads to plaintext recovery attacks (e.g., Bleichenbacher timing attacks).
Auth Bypass: Weaknesses in parsing multi-valued claims (like lists of audiences or space-separated scope claims) can allow authorization bypasses if elements within the collection are not properly normalized and individually validated.
