A vulnerability was found in keycloak. A CSRF attack can be performed in My Resources functionality in the Account Console. The attacker can trick the user to perform operations by using social engineering or any other mean that can result in a request to Keycloak from an untrusted domain.
References: https://issues.jboss.org/browse/KEYCLOAK-10775
If an attacker modifies the SAML Response and removes the <Signature> Sections, the message is still accepted and the message can be modified, allowing the attacker to impersonate any user on the keycloak protected systems by modifying assertations.
