## What is CVE-2026-72654?

CVE-2026-72654 is a medium-severity vulnerability in Elastic Kibana, published on 1 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Execution with Unnecessary Privileges (CWE-250) in the Kibana machine learning feature can lead to information disclosure via Privilege Abuse (CAPEC-122). An operation available to users holding only read access to the machine learning feature was performed with an internal service identity rather than the identity of the requesting user. Such a user could therefore receive data from Elasticsearch indices they are not authorized to read. No Elasticsearch cluster or index privileges are required.

Weakness: CWE-250 (Execution with Unnecessary Privileges)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-72654 and fix it if it is affected.

What it is: CVE-2026-72654 is a medium-severity vulnerability in Elastic Kibana, published on 1 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-72654 in the wild and no public exploit code.

Affected product: Elastic Kibana. 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.
