CVE-2026-22886CVE-2026-22886
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.
