CVE-2026-97147: [OSSA-2026-044] OpenStack Mistral: Four authorization and privilege vulnerabilities in Mistral (CVE-2026-93858, CVE-2026-93860, CVE-2026-93861, CVE-2026-97147))
In OpenStack Mistral through 23.0.0, several of the v2 API write paths resolve the target object with a query that can return another project's resource, then write to it. An authenticated project member can use this to rewrite and un-publish another project's public action definitions and environments. A project administrator can create a workbook whose embedded ad-hoc action or workflow name collides with a resource of another project, which moves that resource into the caller's project and causes the original owner's subsequent updates of it to fail with server errors. Only deployments exposing the Mistral API are affected.

Frequently Asked Questions
Which deployments are exposed?
Only deployments that expose the Mistral API are affected. The issue applies to OpenStack Mistral through 23.0.0.
What access does an attacker need?
An authenticated project member can rewrite or un-publish another project's public action definitions and environments. A project administrator can also exploit name collisions in a workbook's embedded ad-hoc action or workflow to move another project's resource into the administrator's project.
What operational symptoms can indicate exploitation?
A resource may unexpectedly appear in a different project after a workbook with a colliding embedded action or workflow name is created. The original owner may then receive server errors when attempting to update that resource.
