CVE-2026-57214: Broadcom Rabbitmq Server

Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

RabbitMQ is a messaging and streaming broker. Prior to 4.2.5, the RabbitMQ management UI renders the x-internal-purpose queue or exchange argument into an HTML title attribute without proper escaping on the Queues and Exchanges pages, allowing a user with permission to declare a queue or exchange to execute JavaScript in another user's browser. This issue is fixed in version 4.2.5.

Affected products

• Broadcom Rabbitmq Server: from 4.2.0, before 4.2.5 (fixed in 4.2.5)
