CVE-2026-22886

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.
