- RabbitMQ is a multi-protocol messaging and streaming broker. HTTP API did not enforce an HTTP request body
limit, making it vulnerable for denial of service (DoS) attacks with very large messages. An authenticated
user with sufficient credentials can publish a very large messages over the HTTP API and cause target node
to be terminated by an out-of-memory killer-like mechanism. This vulnerability has been patched in
versions 3.11.24 and 3.12.7. (CVE-2023-46118)
