Short explanation
In Envoyproxy’s jwt_authn HTTP filter, versions up to 1.38.0 allow a duplicate header to bypass the JWT requirement, letting requests reach the upstream backend without authentication.
Bypassing authentication enables unauthorized access and data leakage, posing a serious risk to critical infrastructure.
What should be done?
- Follow the official Envoyproxy security advisory
- Apply temporary mitigations until a fixed version is released
- Validate request headers rigorously
- Restrict network access to the service
- Implement security monitoring for anomalies
