CVE-2021-20278
Description
An authentication bypass vulnerability was found in Kiali in versions before 1.31.0 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.
