Affected: Red Hat build of Keycloak 26.4, Red Hat build of Keycloak 26.4.17, Red Hat build of Keycloak 26.6, Red Hat build of Keycloak 26.6.8, Red Hat Single Sign-On 7

A flaw was found in the Keycloak Account REST API where it incorrectly handles session identification. A malicious client owner can manipulate their own security tokens to point to a different user's active session. This allows the attacker to access and modify the victim's account information, potentially leading to a full account takeover by changing the recovery email and resetting the password.
