{"id":"CVE-2026-66069","state":"PUBLISHED","title":"RabbitMQ: Monitoring-tag DELETE of auth-attempt metrics","description":"RabbitMQ is a messaging and streaming broker. Prior to versions 4.1.13, 4.2.7, and 4.3.0, is_authorized/2 uses is_authorized_monitor for all methods. DELETE resets rabbit_core_metrics:reset_auth_attempt_metrics(). Impact is cosmetic (counters only, no log erasure), but inconsistent with rabbit_mgmt_wm_reset.erl which requires admin for the analogous operation. A monitoring-tagged user can reset the per-node authentication-attempt counters via DELETE /api/auth/attempts/:node, erasing evidence of brute-force activity. The sibling endpoint wm_reset requires administrator. Preconditions include Management plugin enabled monitoring tag.
