Summary
Kiali Authentication Bypass vulnerability
Details

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.
