Recurring patterns

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

Auth Bypass: Subject claim validation was added in two separate commits, indicating the check was initially missing and then extended, leaving room for incomplete enforcement on other decode paths.

Auth Bypass: JTI validation was added alongside subject validation, but only in one commit, suggesting other claim-based bypasses may exist if JTI is not checked on all verification paths.

Auth Bypass: The verify_signature option allows skipping signature verification entirely; if a caller passes verify=False, authentication is bypassed regardless of other checks.
