There is no fixed version for RHEL:7 rh-sso7-keycloak-server.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rh-sso7-keycloak-server package and not the rh-sso7-keycloak-server package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in Keycloak that occurs from an error in the re-authentication mechanism within org.keycloak.authentication. This flaw allows hijacking an active Keycloak session by triggering a new authentication process with the query parameter "prompt=login," prompting the user to re-enter their credentials. If the user cancels this re-authentication by selecting "Restart login," an account takeover may occur, as the new session, with a different SUB, will possess the same SID as the previous session.
