The issue allows an unauthenticated attacker to force the password reset process for any user without needing to click the required email verification link. This can result in the attacker gaining full control over target user accounts by directly setting new credentials.","state":0,"publishedAt":"2026-08-18T17:05:07.478+00:00","modifiedAt":"2026-10-23T16:38:40.595+00:00","affected":[{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"rhbk/keycloak-operator-bundle","ranges":[],"versions":[],"rawVersionEvidence":"{\n
