Summary
RabbitMQ management HTTP API accepts request bodies larger than configured max_http_body_size
Details

RabbitMQ is a messaging and streaming broker. Prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5, the rabbitmqmanagement HTTP API accepts oversized valid JSON bodies on withdecode and directrequest paths because readcomplete_body checks the accumulated size before the final chunk but not the final combined size. This issue is fixed in versions 3.13.14, 4.0.19, 4.1.10, and 4.2.5.
