{"schema":"threatline.record/2","record":{"id":"CVE-2026-67218","aliases":["GHSA-34jw-rm7g-hph4"],"summary":"RabbitMQ: Super-stream HTTP creation skips configure-permission check","details":"RabbitMQ is a messaging and streaming broker. Prior to versions 4.0.22, 4.1.11, 4.2.6, and 4.3.0, accept_content/2 at line 56 calls rabbit_stream_manager:create_super_stream/... directly after is_authorized (which only checks the management tag + vhost access via is_authorized_vhost). The stream-protocol equivalent (rabbit_stream_reader.erl create_super_stream handler) calls rabbit_stream_utils:check_super_stream_management_permitted/4 which enforces configure on the exchange and each partition queue. The HTTP handler omits this call entirely. A user with management tag and vhost access , but no configure permission on any resource , can create super-streams (an exchange + N partition stream queues + bindings) via the HTTP API. The native stream-protocol path enforces configure on each resource; the HTTP path does not, creating a privilege escalation from 'can view' to 'can create persistent cluster-wide resources.' Preconditions include rabbitmq_stream_management plugin enabled management tag + vhost access (no resource permissions needed). This issue is fixed in versions 4.0.22, 4.1.11, 4.2.6, and 4.3.0.","categories":["Unclassified"],"product":"rabbitmq-server","vendor":"rabbitmq","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-67218","source_modified_at":"2026-09-24T14:08:57.367Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"rabbitmq-server","vendor":"rabbitmq","versions":[{"version":">= 4.0.0, < 4.0.22","status":"affected"},{"version":">= 4.1.0, < 4.1.11","status":"affected"},{"version":">= 4.2.0, < 4.2.6","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":2.1,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00372,"percentile":0.29998,"score_date":"2026-10-23"},"published_at":"2026-09-23T20:46:33.316Z","modified_at":"2026-09-24T14:08:57.367Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-67218","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-24T14:08:57.367Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-67218","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-34jw-rm7g-hph4","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.2.6","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.3.0","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":"2026-09-24T14:08:46.026271Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-24T14:08:57.367Z","content_hash":"a855076544709f9803bb19965e7c103c119caab7e0f4a12bad7ca358407fe1ff"}}
