CVE-2026-24130 (GCVE-0-2026-24130)

Vulnerability from cvelistv5 – Published: 2026-01-22 22:53 – Updated: 2026-01-23 20:03

Title

Moonraker with LDAP Enabled Allows Malicious Search Filter Injection

Summary

Moonraker is a Python web server providing API access to Klipper 3D printing firmware. 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.

Severity ?

2.7 (Low)

GHSA-3JQF-V4MV-747G

Vulnerability from github – Published: 2026-01-22 18:06 – Updated: 2026-01-23 15:49

Summary

Moonraker affected by LDAP search filter injection

Details

Impact

Instances of Moonraker 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.

Patches

Users should upgrade to Moonraker 0.10.0 which patches this vulnerability.

Workarounds

Admins can set the max_login_attempts option in the [authorization] section to a reasonable value. Any IP attempting to exploit this vulnerability will be locked out after it has reached the specified number of consecutive failed login attempts. This condition is cleared after a Moonraker restart. Note that if an attacker knows a valid user password they can bypass this protection by successfully logging in.

The most secure workaround for users unable to upgrade is to remove the ldap section from moonraker.conf and rely on the built in user authentication.

Severity ?

2.7 (Low)

  "details": "### Impact\n\nInstances of Moonraker 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.\n\n### Patches\n\nUsers should upgrade to Moonraker 0.10.0 which patches this vulnerability.\n\n### Workarounds\n\nAdmins can set the `max_login_attempts` option in the `[authorization]` section to a reasonable value.    Any IP attempting to exploit this vulnerability will be locked out after it has reached the specified number of consecutive failed login attempts.  This condition is cleared after a Moonraker restart.   Note that if an attacker knows a valid user password they can bypass this protection by successfully logging in.\n\nThe most secure workaround for users unable to upgrade is to remove the `ldap` section from `moonraker.conf` and rely on the built in user authentication.",
