{"id":"DEBIAN-CVE-2026-67405","details":"RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, Neither the Web-MQTT handler (deps/rabbitmq_web_mqtt/src/rabbit_web_mqtt_handler.erl:104) nor the Web-STOMP handler (deps/rabbitmq_web_stomp/src/rabbit_web_stomp_handler.erl:102) validates the Origin header on the WebSocket upgrade. Under ssl_cert_login=true, the browser presents the client certificate automatically, so an attacker's JavaScript running in the victim's browser can authenticate as the victim. Preconditions include The non-default configuration use_http_auth=true (Web-STOMP) or ssl_cert_login=true (both plugins) must be enabled. The issue is harmless under the default in-band CONNECT credential configuration.. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0.","modified":"2026-09-25T09:00:17.053117535Z","published":"2026-09-23T21:17:01.663Z","upstream":["CVE-2026-67405"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-67405"}],"affected":[{"package":{"name":"rabbitmq-server","ecosystem":"Debian:12","purl":"pkg:deb/debian/rabbitmq-server?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.10.8-1.1","3.10.8-1.1+deb12u1","3.10.8-2","3.10.8-3","3.10.8-4","3.12.1-1","3.12.1-1.1","4.0.5-1","4.0.5-10","4.0.5-11","4.0.5-12","4.0.5-13","4.0.5-14","4.0.5-2","4.0.5-3","4.0.5-4","4.0.5-5","4.0.5-6","4.0.5-8","4.0.5-9","4.3.0-1","4.3.0-2","4.3.0-3","4.3.2-1","4.3.2-2","4.3.2-3","4.3.2-4","4.3.2-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67405.json"}},{"package":{"name":"rabbitmq-server","ecosystem":"Debian:13","purl":"pkg:deb/debian/rabbitmq-server?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.5-10","4.0.5-11","4.0.5-12","4.0.5-13","4.0.5-14","4.0.5-6","4.0.5-6+deb13u1","4.0.5-6+deb13u2","4.0.5-8","4.0.5-9","4.3.0-1","4.3.0-2","4.3.0-3","4.3.2-1","4.3.2-2","4.3.2-3","4.3.2-4","4.3.2-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67405.json"}},{"package":{"name":"rabbitmq-server","ecosystem":"Debian:14","purl":"pkg:deb/debian/rabbitmq-server?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.0-2"}]}],"versions":["4.0.5-10","4.0.5-11","4.0.5-12","4.0.5-13","4.0.5-14","4.0.5-6","4.0.5-8","4.0.5-9","4.3.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67405.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/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"}]}
