LDAP Injection in Arksine Moonraker

CVE-2026-24130

In versions 0.9.3 and below, instances configured with the "ldap" component enabled are vulnerable to LDAP search filter injection techniques via the login endpoint. The 401 error response message can be used to determine whether or not a search was successful, allowing for brute force methods to discover LDAP entries on the server such as user IDs and user attributes. This issue has been fixed in version 0.10.0.
