Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76878 in the wild and no public exploit code.\n\nAffected product: OpenStack Aodh. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-76878/ (Markdown: https://insights.sbomify.com/CVE-2026-76878/index.md)","id":"CVE-2026-76878","markdown":"https://insights.sbomify.com/CVE-2026-76878/index.md","name":"CVE-2026-76878","record":{"aliases":["DEBIAN-CVE-2026-76878","GHSA-25rc-jgc5-f99w","UBUNTU-CVE-2026-76878","USN-8870-1"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenStack Aodh","requires_auth":"low_privilege","summary":"Non-admin users can bypass project scoping in OpenStack Aodh to list alarms from all projects, exposing sensitive webhook URLs and enabling unauthorized audit triggers in Watcher.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:L/SI:H/SA:L","version":"4.0"},"cwes":[{"id":"CWE-688","name":"Function Call With Incorrect Variable or Reference as Argument"}],"description":"In OpenStack Aodh before 22.0.1, the alarm list API bypasses project scoping when the all_projects query parameter is set to false. The API checks for the presence of the all_projects key rather than its value; a true value enforces the administrator-only policy, but a false value removes the key and skips the branch that normally restricts results to the caller's project. A non-admin user with the reader role can list alarms from all projects, exposing alarm actions containing trust webhook URLs, Heat signal endpoints, project IDs, and user IDs. The parameter can also be combined with a foreign project_id to target a specific project's alarms. A related concern is that OpenStack Watcher does not apply authorization to its webhook trigger endpoint. Any authenticated user who learns an audit's webhook URL, for example from this leaked Aodh alarm metadata, can start an EVENT audit and its associated action plan regardless of their own project or role. The webhook endpoint has lacked policy enforcement since its introduction in the Ussuri release (Watcher 4.0.0).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Missing authorization in Aodh","id":"CVE-2026-76878","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Stack-based Buffer Overflow in Wireshark","id":"CVE-2026-76879"},"packages":[],"prev":{"headline":"Craftplan \u003c 0.5.1 Broken Access Control Information Disclosure via Settings API","id":"CVE-2026-76876"},"products":["Aodh"],"published":"2026-08-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-21","vendors":["OpenStack"]},"summary":"Non-admin users can bypass project scoping in OpenStack Aodh to list alarms from all projects, exposing sensitive webhook URLs and enabling unauthorized audit triggers in Watcher.","url":"https://insights.sbomify.com/CVE-2026-76878/"}
