CVE-2023-46118Network attack vector

Node termination via unbounded HTTP request bodies

Published Oct 24, 2023 · Updated Feb 13, 2025

Resource exhaustion in RabbitMQ Server 3.11.0 through 3.11.23 and 3.12.0 through 3.12.6 allows remote authenticated users to terminate a node. The management HTTP API accepts a message-publish request body without enforcing a size limit, allowing oversized message data to exhaust node memory. Exploitation requires an authenticated account with sufficient publishing rights, and the resulting exhaustion causes an out-of-memory-killer-like node termination.
