{"schema":"threatline.record/2","record":{"id":"CVE-2026-67223","aliases":["GHSA-9x7r-g78c-5835"],"summary":"RabbitMQ: LDAP DN injection via unescaped substitution","details":"RabbitMQ is a messaging and streaming broker. The advisory establishes affected 3.13, 4.0, 4.1, 4.2, and 4.3 maintenance lines but contains conflicting first-fixed versions for the 3.13, 4.0, and 4.1 lines. fill/2 substitutes ${username} into user_dn_pattern without RFC 4514 DN escaping, allowing a crafted username to alter the LDAP bind DN and potentially select a different directory entry. Exploitation requires rabbitmq_auth_backend_ldap with a user_dn_pattern containing ${username}, a directory layout in which the injected suffix resolves usefully, and a password valid for the resulting DN. The advisory body identifies 3.13.15, 4.0.20, 4.1.11, 4.2.9, and 4.3.3 as fixed, while structured metadata identifies 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3. No fixed-version assertion is certifiable until a curator resolves this conflict.","categories":["Unclassified"],"product":"rabbitmq-server","vendor":"rabbitmq","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-67223","source_modified_at":"2026-09-25T17:51:08.133Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"rabbitmq-server","vendor":"rabbitmq","versions":[{"version":">= 3.13.0, < 3.13.18","status":"affected"},{"version":">= 4.0.0, < 4.0.23","status":"affected"},{"version":">= 4.1.0, < 4.1.14","status":"affected"},{"version":">= 4.2.0, < 4.2.9","status":"affected"},{"version":">= 4.3.0, < 4.3.3","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00357,"percentile":0.28215,"score_date":"2026-10-23"},"published_at":"2026-09-25T16:15:08.185Z","modified_at":"2026-09-25T17:51:08.133Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-67223","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T17:51:08.133Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-67223","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-9x7r-g78c-5835","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/commit/ad3ca47accd313a4a0dbcbbe17bf60fc8f4b2614","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/commit/b54056e59b7fd3a2d7f07dfaba95f026e138eee8","tags":["x_refsource_MISC"]},{"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":"2026-09-25T17:50:52.557104Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T17:51:08.133Z","content_hash":"dca60e903147fc614223e701ccb17b36aa8cbca4f9fcfbc04e1127f58f681e8d"}}
