{"id":"BIT-rabbitmq-2026-67230","summary":"RabbitMQ: Web-STOMP unbounded pre-auth accumulation","details":"RabbitMQ is a messaging and streaming broker. From 3.13.0 until 3.13.15, 4.0.20, 4.1.11, and 4.2.6, the Web STOMP WebSocket handler enforced neither max_frame_size nor login_timeout before authentication, allowing an unauthenticated client to keep a connection alive with a slow stream of small frames and accumulate unbounded pre-authentication state. The rabbitmq_web_stomp plugin must be enabled, and no authentication is required to reach the vulnerable path. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.","aliases":["CVE-2026-67230","GHSA-7v63-j4gm-p4rh"],"modified":"2026-10-01T10:10:43.334260779Z","published":"2026-10-01T09:33:22.746Z","database_specific":{"cpes":["cpe:2.3:a:vmware:rabbitmq:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-server/commit/0b4080fa5d6f797b6331d0ce1db2b4bacd34560e"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-server/commit/8138edae6d2beaafe699a41a754d17420bdc2068"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-server/commit/c1000ba89052608c01c052d98016403ba6e92222"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6"},{"type":"WEB","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-7v63-j4gm-p4rh"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67230"}],"affected":[{"package":{"name":"rabbitmq","ecosystem":"Bitnami","purl":"pkg:bitnami/rabbitmq"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.13.0"},{"fixed":"3.13.15"},{"introduced":"4.0.0"},{"fixed":"4.0.20"},{"introduced":"4.1.0"},{"fixed":"4.1.11"},{"introduced":"4.2.0"},{"fixed":"4.2.6"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/rabbitmq/BIT-rabbitmq-2026-67230.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
