A flaw was found in keycloak where keycloak may fail to logout user session if the logout request comes from external SAML identity provider and Principal Type is set to Attribute [Name].
According to WASC, “Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization.”
