{"id":"DEBIAN-CVE-2026-67406","details":"RabbitMQ is a messaging and streaming broker. From 4.0.0 until 4.3.3, 4.2.9, 4.1.14, and 4.0.23, Shovel does not format state logged by the crash reporter and can leave unencrypted credentials in a crash dump file. the shovel worker genserver processes does not implement the formatstatus/2 callback. When these processes crash (e.g., due to network partitions, connection failures), the OTP SASL error handler writes the full process state , including plaintext AMQP passwords and URIs , to the error log. This is particularly severe for the shovel worker, which stores deobfuscated plaintext URIs (including amqp://user:password@host format) in its genserver state for the entire process Automatic Credential Exposure: Shovel worker crashes (common during network partitions) automatically write plaintext upstream/downstream passwords to error logs No Special Configuration Needed: Unlike DEBUG logging, SASL error reports are always active Broad. This issue is fixed in versions 4.3.3, 4.2.9, 4.1.14, and 4.0.23.","modified":"2026-10-23T16:03:09.067962549Z","published":"2026-09-25T17:17:12.477Z","upstream":["CVE-2026-67406"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-67406"}],"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","4.3.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67406.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","4.3.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67406.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":"4.3.6-1"}]}],"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","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-2026-67406.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
