Descriptions

A flaw was found in Keycloak. When an Active Directory user resets their password, the system updates it without performing an LDAP bind to validate the new credentials against AD. This vulnerability allows users whose AD accounts are expired or disabled to regain access in Keycloak, bypassing AD restrictions. The issue enables authentication bypass and could allow unauthorized access under certain conditions.

New images are available for Red Hat build of Keycloak 26.0.10 and Red Hat build of Keycloak 26.0.10 Operator, running on OpenShift Container Platform. Issues addressed include bypass and improper authorization vulnerabilities.

*Credits: Red Hat would like to thank Dwayne Du for reporting this issue.
