Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Auto-configuration classes failed to mandate critical JWT validation parameters (audience and issuer claims) by default, leaving environments susceptible to token reuse across different resources if users did not explicitly declare verification properties.
Auth Bypass: Weak IAP token assertion validation on the `JwtDecoder` class could allow attackers to bypass authentication by presenting valid Google-signed tokens that were intended for other target resources or applications.
Privilege Escalation: Over-scoped Google API credentials for Cloud SQL instances requested platform-wide access tokens instead of narrow scope-specific ones, potentially exposing administrative actions on other GCP resources (such as Cloud Storage or Pub/Sub) if credentials were leaked.
