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.","categories":["Unclassified"],"product":"rabbitmq-server","vendor":"rabbitmq","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-67406","source_modified_at":"2026-09-25T17:00:54.175Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"rabbitmq-server","vendor":"rabbitmq","versions":[{"version":">= 4.3.0, < 4.3.3","status":"affected"},{"version":">= 4.2.0, < 4.2.9","status":"affected"},{"version":">= 4.1.0, < 4.1.14","status":"affected"},{"version":">= 4.0.0, < 4.0.23","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":4.6,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00286,"percentile":0.20062,"score_date":"2026-10-23"},"published_at":"2026-09-25T16:34:06.122Z","modified_at":"2026-09-25T17:00:54.175Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-67406","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T17:00:54.175Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-67406","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/security/advisories/GHSA-q44f-9vc5-grh7","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.9","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.3.3","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-25T17:00:45.529742Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T17:00:54.175Z","content_hash":"02cbbea9fb7fd5e85c4003ee2b739eedaedf98cbcbb38887a559e5ffa93a15b7"}}
