CVE-2026-67415

RabbitMQ is a messaging and streaming broker. From 4.2.0 until 4.2.9 and 4.3.3, the Shovel parameter parser converted attacker-controlled runtime parameter values into non-garbage-collected Erlang atoms before bounding them or checking a fixed allowlist. Exploitation requires network access to th...

CVE-2026-67238

A flaw was found in RabbitMQ, a messaging and streaming broker. An authenticated AMQP Advanced Message Queuing Protocol client can trigger an atom-table exhaustion by sending specially crafted reply-to queue names for decoding. This can lead to the entire Erlang Virtual Machine VM crashing,...

CVE-2026-67229

A flaw was found in RabbitMQ, a messaging and streaming broker. An administrator with appropriate privileges can trigger a Denial of Service DoS by importing a specially crafted definitions file. This file, containing a large number of unique metadata keys, causes the system to exhaust its atom...

CVE-2026-67228

A flaw was found in RabbitMQ. An authorized policymaker can exploit this vulnerability by issuing a large number of requests with distinct component values to the runtime-parameters lookup path. This action coerces attacker-supplied strings into new atoms, eventually exhausting the Erlang atom...
