CVE-2026-24130: Moonraker with LDAP Enabled Allows Malicious Search Filter Injection

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.

Security readout for executives and security teams

Plain-English summary

CVE-2026-24130 affects Moonraker, the API server used with Klipper 3D printing firmware. When LDAP authentication is enabled, an unauthenticated attacker may infer LDAP directory information through login error behavior. The published severity is low, but internet-exposed or shared-environment printer services should still be reviewed.

Executive priority

Treat as routine but timely maintenance. Prioritize internet-facing or shared Moonraker deployments using LDAP. The likely business impact is limited directory information exposure, but exposed authentication services should not remain on vulnerable versions.

Technical view

Moonraker versions 0.9.3 and below are vulnerable when the ldap component is enabled. The login endpoint allows LDAP search filter injection, and 401 error responses can reveal whether searches succeeded. This can support brute forcing of LDAP entries such as user IDs and attributes. Fixed in Moonraker 0.10.0.

Likely exposure

Exposure is limited to Arksine Moonraker deployments below 0.10.0 with the ldap component enabled. Risk increases if the Moonraker login endpoint is reachable from untrusted networks. Non-LDAP configurations are not described as affected in the provided sources.

Exploitation context

The CVE record lists network attack vector, low complexity, no privileges, and no user interaction. Sources describe information disclosure through LDAP filter injection, not code execution or service takeover. There is no KEV listing or provided evidence of active exploitation.

Researcher notes

The issue maps to CWE-90 and CWE-209. The observable oracle is the 401 response behavior after crafted LDAP search filters. Avoid intrusive testing against production authentication systems; validate primarily through version, configuration, and exposure review.

Mitigation direction

  • Upgrade Moonraker to version 0.10.0 or later.
  • If LDAP is not required, disable the ldap component.
  • Restrict Moonraker login access to trusted networks where possible.
  • Review vendor advisory and release notes for deployment-specific guidance.

Validation and detection

  • Inventory Moonraker instances and record installed versions.
  • Check whether the ldap component is enabled.
  • Confirm the login endpoint is not exposed to untrusted networks.
  • Verify upgraded systems report Moonraker 0.10.0 or later.
