It was found that SAML authentication in Keycloak 3.4.3.Final incorrectly authenticated expired certificates. A malicious user could use this to access unauthorized data or possibly conduct further attacks.

Weakness

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
