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-2026-20943 in the wild and no public exploit code.\n\nAffected product: Microsoft Office. 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-2026-20943/ (Markdown: https://insights.sbomify.com/CVE-2026-20943/index.md)","id":"CVE-2026-20943","markdown":"https://insights.sbomify.com/CVE-2026-20943/index.md","name":"CVE-2026-20943","record":{"aliases":["GHSA-7mcc-vv62-fp9q"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Office","requires_auth":"none","summary":"An attacker can execute arbitrary code locally by exploiting an untrusted search path in Microsoft Office.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"office","vendor":"microsoft"},{"product":"office_deployment_tool","vendor":"microsoft"},{"product":"sharepoint_server","vendor":"microsoft"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-426","name":"Untrusted Search Path"}],"description":"Untrusted search path in Microsoft Office allows an unauthorized attacker to execute code locally.","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":"Microsoft Office Click-To-Run Remote Code Execution Vulnerability","id":"CVE-2026-20943","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:office","products":["microsoft:office","microsoft:sharepoint_server"],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Word Remote Code Execution Vulnerability","id":"CVE-2026-20944"},"packages":[],"prev":{"headline":"Microsoft Edge (Chromium-based) Spoofing Vulnerability","id":"CVE-2026-20942"},"products":["Microsoft Office 2016","Microsoft Office Deployment Tool","Microsoft SharePoint Enterprise Server 2016","Microsoft SharePoint Server 2019","Microsoft SharePoint Server Subscription Edition"],"published":"2026-01-13","related":[{"cvss_score":8.8,"headline":"Microsoft Office Memory Corruption","id":"CVE-2018-0798","kev_date_added":"2021-11-03","published":"2018-01-10"},{"cvss_score":8.8,"headline":"Microsoft Office Uninitialized Memory Use","id":"CVE-2015-1770","kev_date_added":"2022-03-28","published":"2015-06-10"},{"cvss_score":8.8,"headline":"Microsoft Word Malformed Object Pointer","id":"CVE-2006-2492","kev_date_added":"2022-06-08","published":"2006-05-20"},{"cvss_score":7.8,"headline":"Microsoft Office Memory Corruption","id":"CVE-2018-0802","kev_date_added":"2021-11-03","published":"2018-01-10"},{"cvss_score":7.8,"headline":"Microsoft Office Memory Corruption","id":"CVE-2017-11882","kev_date_added":"2021-11-03","published":"2017-11-15"},{"cvss_score":7.8,"headline":"Microsoft Office Remote Code Execution","id":"CVE-2017-8570","kev_date_added":"2022-02-25","published":"2017-07-11"},{"cvss_score":7.8,"headline":"Microsoft Office Use-After-Free","id":"CVE-2017-0261","kev_date_added":"2022-03-03","published":"2017-05-12"}],"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":"2026-07-30","vendors":["Microsoft"]},"summary":"An attacker can execute arbitrary code locally by exploiting an untrusted search path in Microsoft Office.","url":"https://insights.sbomify.com/CVE-2026-20943/"}
