CVE-2026-66069: RabbitMQ unauthorized auth-attempt metrics reset

CVE-2026-66069 · Severity: info · Published 2026-09-23

RabbitMQ's management API allows users with monitoring privileges to reset authentication attempt counters without requiring administrator access. This inconsistency permits a monitoring-tagged user to erase forensic evidence of brute-force login attempts, reducing visibility into attack patterns. While the impact is limited to counter visibility (no actual logs are deleted), it undermines security monitoring and audit compliance in deployments relying on these metrics to detect intrusion activity.

Technologies: VMware RabbitMQ. Vendors: VMware.

Technical details

The is_authorized/2 function in RabbitMQ incorrectly uses is_authorized_monitor for all methods on the DELETE /api/auth/attempts/:node endpoint, allowing users with a monitoring tag to call rabbit_core_metrics:reset_auth_attempt_metrics(). The sibling wm_reset endpoint correctly requires administrator privileges for the equivalent operation. This authorization bypass is a privilege escalation flaw affecting the management plugin when enabled; monitoring is a low-privilege tag and should not permit counter manipulation meant for administrators.
