RabbitMQ versions prior to 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0 contain a vulnerability in the consistent-hash exchange plugin where the add_binding/3 function parses the routing key as an integer weight without an upper bound. This allows a user with write permission on a consistent-hash exchange and read permission on a queue to create a binding with an arbitrarily large weight, causing excessive memory allocation (~800 MB for weight 100000000) on all cluster nodes. The allocated list is persisted cluster-wide and survives restarts, potentially leading to resource exhaustion. The issue is fixed in the specified versions.
