Unauthorized maintenance setting change in OpenStack Ironic (CVE-2026-89419)

Source agreement

Evidence confidence

Short explanation

In OpenStack Ironic versions prior to 39.0.1, a user can send a PATCH to /v1/nodes/{ident} and change a node’s maintenance flag without using the dedicated maintenance endpoint, allowing unauthorized configuration changes.

Why does it matter?

The ability to alter maintenance status can lead to service disruption and unauthorized control over infrastructure management.

What should be done?

  • Follow the vendor advisory
  • Upgrade affected installations to at least 39.0.1
  • Restrict network access to the API
  • Monitor and validate PATCH requests

OpenStack Ironic before 39.0.1 sometimes allows a user to change the maintenance setting on a node via PATCH to /v1/nodes/{ident} - in other words, not using the specific maintenance endpoint.
