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.

Pivotal RabbitMQ, versions prior to v3.7.18, and RabbitMQ for PCF, versions 1.15.x prior to 1.15.13, versions 1.16.x prior to 1.16.6, and versions 1.17.x prior to 1.17.3, contain two components, the virtual host limits page, and the federation management UI, which do not properly sanitize user input. A remote authenticated malicious user with administrative access could craft a cross site scripting attack that would gain access to virtual hosts and policy management information.
