How to fix?

There is no fixed version for RHEL:9 keycloak-services.

NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-services package and not the keycloak-services package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in the first-broker-login flow of the Keycloak identity management service. When a user links a social identity provider account to their local account, the verification proof generated is not strictly bound to the specific upstream identity being verified. This allows an attacker with a different account on the same social provider to intercept the process and link their own account to the victim's local profile, gaining unauthorized access.
