CVE-2023-46118

Name of the Vulnerable Software and Affected Versions RabbitMQ versions prior to 3.11.24 RabbitMQ versions prior to 3.12.7

Description The issue is related to the HTTP API of RabbitMQ, a multi-protocol messaging and streaming broker, which did not enforce an HTTP request body limit. This made it vulnerable to denial of service (DoS) attacks with very large messages. An authenticated user with sufficient credentials can publish very large messages over the HTTP API, causing the target node to be terminated by an "out-of-memory killer"-like mechanism.

Recommendations For RabbitMQ versions prior to 3.11.24, update to version 3.11.24 or later to resolve the issue. For RabbitMQ versions prior to 3.12.7, update to version 3.12.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the HTTP API to minimize the risk of exploitation.
