Vendor Workaround
To mitigate this issue, Red Hat Quay administrators should ensure that federated robot authentication is configured with specific audiences to enable 'verify_aud' enforcement. Additionally, review and update existing federation configurations to explicitly include and enforce 'azp' and 'sub' claims, preventing bypasses when these claims are absent. Refer to Red Hat Quay documentation for detailed configuration steps. A restart of affected Quay services may be required after configuration changes.

| Description | A flaw was found in Red Hat Quay's JWT (JSON Web Token) validation for federated robot accounts and single sign-on (SSO) authentication. Multiple issues related to audience verification and the enforcement of `azp` and `sub` claims were identified. These flaws could allow an attacker with a validly-signed token from the same identity provider to bypass configured security restrictions. This bypass could lead to unauthorized access by circumventing intended audience, subject, or authorized-client limitations. | |
