An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-67218 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- rabbitmq (Bitnami): affected from 4.0.0; fixed in 4.0.22, 4.1.11, 4.2.6\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-67218/ (Markdown: https://insights.sbomify.com/CVE-2026-67218/index.md)","id":"CVE-2026-67218","markdown":"https://insights.sbomify.com/CVE-2026-67218/index.md","name":"CVE-2026-67218","record":{"aliases":["BIT-rabbitmq-2026-67218","DEBIAN-CVE-2026-67218","GHSA-34jw-rm7g-hph4","UBUNTU-CVE-2026-67218"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"RabbitMQ message broker","requires_auth":"high_privilege","summary":"Attackers with management access can create super-streams via HTTP API without configure permissions, escalating privileges to create persistent cluster resources.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"rabbitmq_server","vendor":"broadcom"}],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"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).
