CVE-2026-66069
Description
A flaw was found in RabbitMQ. A user with a monitoring tag, when the Management plugin is enabled, can reset the per-node authentication-attempt counters. This action, which should be restricted to administrators, allows the monitoring-tagged user to erase evidence of brute-force login attempts. While the impact is primarily cosmetic, it creates an inconsistency in access control for a sensitive operation.
Statement
Red Hat rates this flaw MODERATE in products that ship affected RabbitMQ builds. A monitoring-tagged user can reset authentication-attempt counters through the Management API without administrator permission. Broker logs remain intact, so the impact is limited to tampering with security metrics.
Mitigation
Restrict Management API access and monitoring-tag accounts, or disable the Management plugin where it is not needed.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
