It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-1636 in the wild and no public exploit code.\n\nAffected product: Lenovo Service Bridge. 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-2026-1636/ (Markdown: https://insights.sbomify.com/CVE-2026-1636/index.md)","id":"CVE-2026-1636","markdown":"https://insights.sbomify.com/CVE-2026-1636/index.md","name":"CVE-2026-1636","record":{"aliases":["GHSA-qpgx-vhr9-cwj5"],"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 Service Bridge","requires_auth":"low_privilege","summary":"A local authenticated user can execute code with elevated privileges via DLL hijacking in Lenovo Service Bridge.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"service_bridge","vendor":"lenovo"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"A potential DLL hijacking vulnerability was reported in Lenovo Service Bridge that, under certain conditions, could allow a local authenticated user to execute 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":"Privilege escalation in Service Bridge","id":"CVE-2026-1636","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Tenda AC21 AdvSetMacMtuWan fromAdvSetMacMtuWan stack-based overflow","id":"CVE-2026-1637"},"packages":[],"prev":{"headline":"Subitem AL Slider \u003c= 1.0.0 - Reflected Cross-Site Scripting via $_SERVER['PHP_SELF']","id":"CVE-2026-1634"},"products":["Service Bridge"],"published":"2026-04-15","related":[{"cvss_score":8.8,"headline":"Code injection in Service Bridge","id":"CVE-2019-6167","kev_date_added":null,"published":"2019-06-26"},{"cvss_score":8.8,"headline":"Code injection in Service Bridge","id":"CVE-2019-6168","kev_date_added":null,"published":"2019-06-26"},{"cvss_score":6.5,"headline":"Information disclosure in Service Bridge","id":"CVE-2019-6169","kev_date_added":null,"published":"2019-06-26"},{"cvss_score":5.4,"headline":"Cross-site request forgery in Service Bridge","id":"CVE-2019-6166","kev_date_added":null,"published":"2019-06-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-04-16","vendors":["Lenovo"]},"summary":"A local authenticated user can execute code with elevated privileges via DLL hijacking in Lenovo Service Bridge.","url":"https://insights.sbomify.com/CVE-2026-1636/"}
