{"schemaVersion":3,"id":"CVE-2026-67406","aliases":["UBUNTU-CVE-2026-67406","DEBIAN-CVE-2026-67406"],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-09-25T16:34:06.122Z","modified":"2026-09-25T17:00:54.175Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":4.6,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"OSV
