Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The core API authenticator has been patched 9 times for signature and token bypasses, indicating a high-risk attack surface where subtle payload/parameter handling errors enable replay or forgery.
Auth Bypass: JWT verification was repeatedly flawed: used private key for decoding, lacked claim verification, and allowed algorithm confusion. These are classic critical auth bypasses.
Auth Bypass: Multiple 2FA bypasses in Google Authenticator setup/verification flow, including missing checks on show/update actions and session unlock issues.
