Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Client-supplied session claims (memberships, user fields) were trusted, enabling arbitrary session takeover and mass assignment; fixed by server-side re-derivation and field allowlisting.
Auth Bypass: Integrity JWT verification lacked audience and environment-specific issuer/JWKS validation, allowing acceptance of tokens from wrong environment or audience.
Auth Bypass: Nullifier hash normalization gaps (case/prefix/padding) allowed bypassing uniqueness and verification limits; also signal hash encoding bypass.
