## Summary

- **CVE ID:** CVE-2026-22886
- **Severity:** CRITICAL
- **CVSS Score:** 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
- **CWE:** CWE-1392, CWE-1393, CWE-1391

## 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.

## Affected Products
