It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20037 in the wild and no public exploit code.\n\nAffected product: Cisco Unified Computing System (Managed). 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-2026-20037/ (Markdown: https://insights.sbomify.com/CVE-2026-20037/index.md)","id":"CVE-2026-20037","markdown":"https://insights.sbomify.com/CVE-2026-20037/index.md","name":"CVE-2026-20037","record":{"aliases":["GHSA-qwj7-2gpw-fvvg"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco UCS Manager","requires_auth":"low_privilege","summary":"An authenticated local attacker with read-only privileges can escalate privileges to modify files and perform unauthorized actions on Cisco UCS Manager.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-250","name":"Execution with Unnecessary Privileges"}],"description":"A vulnerability in the NX-OS CLI privilege levels of Cisco UCS Manager Software could allow an authenticated, local attacker with read-only privileges to modify files and perform unauthorized actions on an affected system.\r\n\u0026nbsp;\r\nThis vulnerability exists because unnecessary privileges are given to the user.
