RabbitMQ versions 3.8.x prior to 3.8.7 are prone to a Windows-specific binary planting security vulnerability that allows for arbitrary code execution. An attacker with write privileges to the RabbitMQ installation directory and local access on Windows could carry out a local binary hijacking (planting) attack and execute arbitrary code.

Pivotal RabbitMQ, versions 3.7.x prior to 3.7.21 and 3.8.x prior to 3.8.1, and RabbitMQ for Pivotal Platform, 1.16.x versions prior to 1.16.7 and 1.17.x versions prior to 1.17.4, contain a web management plugin that is vulnerable to a denial of service attack. The "X-Reason" HTTP Header can be leveraged to insert a malicious Erlang format string that will expand and consume the heap, resulting in the server crashing.
