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-2026-6387 in the wild and no public exploit code.\n\nAffected product: Lenovo System Update. 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-2026-6387/ (Markdown: https://insights.sbomify.com/CVE-2026-6387/index.md)","id":"CVE-2026-6387","markdown":"https://insights.sbomify.com/CVE-2026-6387/index.md","name":"CVE-2026-6387","record":{"aliases":["GHSA-5j74-5rwg-pcwv"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lenovo System Update","requires_auth":"low_privilege","summary":"A local authenticated user can bypass authentication in Lenovo System Update to execute arbitrary code with elevated privileges.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"A potential authentication bypass vulnerability was reported in Lenovo System Update that could allow a local authenticated user to execute arbitrary code with elevated privileges.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Auth bypass in System Update","id":"CVE-2026-6387","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Argocd-image-updater: argocd image updater: cross-namespace privilege escalation via insufficient namespace validation","id":"CVE-2026-6388"},"packages":[],"prev":{"headline":"Missing large page handling in pmap_pkru_update_range()","id":"CVE-2026-6386"},"products":["System Update"],"published":"2026-08-13","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":"total"},"state":"PUBLISHED","updated":"2026-08-13","vendors":["Lenovo"]},"summary":"A local authenticated user can bypass authentication in Lenovo System Update to execute arbitrary code with elevated privileges.","url":"https://insights.sbomify.com/CVE-2026-6387/"}
