AI-suggested

Upgrade RabbitMQ to version 3.13.14, 4.0.19, 4.1.10, or 4.2.5 or later to apply the official fix for this vulnerability. No other mitigation is indicated by the vendor advisory.

Description

RabbitMQ versions prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5 contain a vulnerability in the rabbitmq_management HTTP API where oversized valid JSON bodies are accepted improperly. This occurs due to incomplete size checks in the read_complete_body function, potentially leading to denial of service. The issue has been fixed in the specified versions.
