CVE-2026-57215: Broadcom Rabbitmq Server

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

RabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6, RabbitMQ allows foreign bindings to amq.rabbitmq.reply-to destinations because volatile direct-reply-to queues can be accepted at bind and route time but are missing from Khepri-backed deletion checks, leaving persistent route entries after unbind. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.

Affected products

• Broadcom Rabbitmq Server: from 3.13.0, before 4.2.6 (fixed in 4.2.6)
