A broker peer can therefore send a method frame whose payload is larger than the negotiated `frame_max`, have it allocated and decoded, and complete the connection handshake instead of being rejected as a protocol violation.\n\n*Reported by Team Atlanta.*","id":"GHSA-5xwg-cfvj-gff5","modified":"2026-09-10T03:51:13.134044568Z","published":"2026-08-18T16:36:29Z","references":[{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-java-client/security/advisories/GHSA-5xwg-cfvj-gff5"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-java-client/pull/1994"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-java-client/pull/1995"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-java-client/commit/08790f09686173eb17b48d08a25edcb32e71a591"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-java-client/commit/b491075f42e89967610c40beded68d3680cfd472"},{"type":"PACKAGE","url":"https://github.com/rabbitmq/rabbitmq-java-client"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-java-client/releases/tag/v5.33.0"}],"schema_version":"1.9.0","severity":[{"score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N","type":"CVSS_V4"}],"summary":"RabbitMQ Java client accepts broker frames larger than the negotiated AMQP frame_max"}
