CVE-2026-67238 RabbitMQ: Atom-table exhaustion via reply-to queue name decoding

RabbitMQ is a messaging and streaming broker. Prior to versions 4.2.7 and 4.3.1, rabbitpidcodec:decomposefrombinary/1 parses a caller-supplied ETF-encoded binary and calls binarytoatomNode, utf8 on the node-name field. It is reached from rabbitvolatilequeue:pidfromname/2, which is invoked for any...

rabbitmq-server: RabbitMQ: Denial of Service via atom table exhaustion in stream chunk_selector

A flaw was found in RabbitMQ. An authenticated stream client with read access to any stream can exploit a vulnerability in the getchunkselector/1 function. This function processes a client-supplied chunkselector property without proper validation, leading to an atom table exhaustion. Successful...

rabbitmq-server: RabbitMQ: Denial of Service due to atom-table exhaustion via reply-to queue name decoding

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,...
