CVE-2026-93860
In OpenStack Mistral through 23.0.0, the /v2/maintenance API controller clears the request context and calls the maintenance service directly without any policy enforcement.
Overview
CVE-2026-93860 is a known-severity vulnerability. It was published on October 8, 2026.
Technical description
In OpenStack Mistral through 23.0.0, the /v2/maintenance API controller clears the request context and calls the maintenance service directly without any policy enforcement. Any holder of a valid Mistral token, regardless of assigned role, can read and change the service's cluster-wide maintenance state. Setting the state to PAUSED stops processing of new workflow and execution objects across all tenant projects until an operator restores it.
