Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
TLS Certificate Validation Bypass: Hostname validation historically only checked one field (SAN or CN), allowing a certificate valid for a different host to be accepted. The fix added fallback validation, but any refactor of checkServerTrusted could regress this.
Authentication Bypass via Expired Token: Tokens were used until exact expiration, allowing a race where an expired token could still authenticate. The fix refreshes 4 minutes early, but any change to refresh timing or credential caching could reintroduce the bypass.
