## What is CVE-2026-22886?

CVE-2026-22886 is a critical vulnerability in Eclipse OpenMQ, published on 3 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

OpenMQ exposes a TCP-based management service (imqbrokerd) that by default requires
authentication. However, the product ships with a default administrative account (admin/
admin) and does not enforce a mandatory password change on first use. After the first
successful login, the server continues to accept the default password indefinitely without
warning or enforcement.

In real-world deployments, this service is often left enabled without changing the default
credentials. As a result, a remote attacker with access to the service port could authenticate
as an administrator and gain full control of the protocol’s administrative features.

Weakness: CWE-1393 (Use of Default Password), CWE-1392 (Use of Default Credentials), CWE-1391 (Use of Weak Credentials)

Check this codebase for CVE-2026-22886 and fix it if it is affected.

What it is: CVE-2026-22886 is a critical vulnerability in Eclipse OpenMQ, published on 3 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-22886 in the wild and no public exploit code.

Affected product: Eclipse OpenMQ. 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.
