CVE-2026-66069— RabbitMQ: Monitoring-tag DELETE of auth-attempt metrics
Quick assessment
Affected
rabbitmq rabbitmq-server
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
RabbitMQ 是一个消息和流式代理服务器。在版本 4.1.13、4.2.7 和 4.3.0 之前， 函数对所有方法都使用了 。执行 DELETE 请求会重置 。该漏洞的影响仅限于计数器的显示问题（无日志擦除），但与 中要求管理员权限的类似操作不一致。拥有监控标签的用户可以通过向 发送请求，重置每个节点的身份验证尝试计数器，从而抹去暴力破解行为的证据。而对应的另一个端点 则需要管理员权限才能使用。前提条件是需要启用 Management 插件并拥有监控标签。此问题已在版本 4.1.13、4.2.7 和 4.3.0

Vulnerability Title
RabbitMQ: Monitoring-tag DELETE of auth-attempt metrics
Source: CVE Program / CVE List V5
Vulnerability 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. This issue is fixed in versions 4.1.13, 4.2.7, and 4.3.0.
