Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Unverified email addresses from Google's response were historically trusted to populate the authenticated user identity, enabling potential account takeover if an attacker could register an unverified email matching a target user.
Auth Bypass: Lack of explicit JWT assertion verification (such as expiration, 'not before', 'issued at', issuer, and audience) allowed potentially forged, expired, or generic tokens to bypass validation.
Auth Bypass: Failure to validate the Hosted Domain ('hd') claim of a Google account against the expected domain filter allowed unauthorized external Google accounts to authenticate.
