CVE-2026-22886 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. EPSS estimates a 0.40% chance of exploitation in the next 30 days.

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.
