CVE-2026-66079

Prior to versions 3.13.15 , 4.0.20 , 4.1.11 , and 4.2.6 , RabbitMQ is vulnerable to a Denial of Service (DoS) attack due to an issue in the parse_array_primitive/2 function. The parser incorrectly handles constructor 0x45 (list0) , returning an element with a byte-width of zero. This allows an un...
