Doc Text: |
An authentication bypass vulnerability was found in Kiali when the authentication strategy `OpenID` is used. When RBAC is enabled, Kiali assumes that some of the token validation is handled by the underlying cluster. When OpenID `implicit flow` is used with RBAC turned off, this token validation doesn't occur, and this allows a malicious user to bypass the authentication.

External References: https://kiali.io/news/security-bulletins/kiali-security-002/ Acknowledgments: Name: the Kiali Security Group Statement: OpenShift ServiceMesh (OSSM) Kiali is configured to delegate authorization to the OpenShift's RBAC user rights and the OpenID authentication strategy is not supported, therefore it is marked `not affected`. |
