## What is CVE-2026-97147?

CVE-2026-97147 is a high-severity missing authorization vulnerability in OpenStack Mistral, published on 8 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-863 (Incorrect Authorization)

What it is: CVE-2026-97147 is a high-severity missing authorization vulnerability in OpenStack Mistral, published on 8 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-97147 exists.

Affected product: OpenStack Mistral. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
