CVE-2021-20278
May 28, 2021
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.
