CVE-2026-57214 Details
Description
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.
A stored cross-site scripting vulnerability has been identified in the RabbitMQ management UI, affecting versions 4.2.0 prior to 4.2.5. The issue arises because the UI renders the 'x-internal-purpose' queue or exchange argument directly into an HTML title attribute without proper escaping. This flaw allows users with permission to declare queues or exchanges to execute JavaScript in the browsers of other users viewing the Queues or Exchanges pages. The vulnerability exists in the RabbitMQ management plugin, which is included by default in the RabbitMQ server.
Users can upgrade to RabbitMQ version 4.2.5, where this vulnerability has been fixed.
