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-2026-42832 in the wild and no public exploit code.\n\nAffected product: Microsoft Excel. 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-2026-42832/ (Markdown: https://insights.sbomify.com/CVE-2026-42832/index.md)","id":"CVE-2026-42832","markdown":"https://insights.sbomify.com/CVE-2026-42832/index.md","name":"CVE-2026-42832","record":{"aliases":["GHSA-857p-384w-97mc"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Office suite","requires_auth":"none","summary":"An unauthorized attacker can perform local spoofing in Microsoft Office due to improper access control, requiring a security patch.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"excel","vendor":"microsoft"},{"product":"office","vendor":"microsoft"},{"product":"office_long_term_servicing_channel","vendor":"microsoft"},{"product":"word","vendor":"microsoft"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Improper access control in Microsoft Office allows an unauthorized attacker to perform spoofing 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 Spoofing Vulnerability","id":"CVE-2026-42832","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:excel","products":["microsoft:excel","microsoft:office","microsoft:office_long_term_servicing_channel","microsoft:word"],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-42833"},"packages":[],"prev":{"headline":"Microsoft Office Remote Code Execution Vulnerability","id":"CVE-2026-42831"},"products":["Microsoft Excel for Android","Microsoft Office LTSC for Mac 2021","Microsoft Office LTSC for Mac 2024","Microsoft Word for Android"],"published":"2026-05-12","related":[{"cvss_score":8.8,"headline":"Microsoft Excel Remote Code Execution","id":"CVE-2019-1297","kev_date_added":"2022-03-03","published":"2019-09-11"},{"cvss_score":8.8,"headline":"Microsoft Office Remote Code Execution","id":"CVE-2009-0238","kev_date_added":"2026-04-14","published":"2009-02-25"},{"cvss_score":7.8,"headline":"Microsoft Office Security Feature Bypass","id":"CVE-2016-7262","kev_date_added":"2022-03-03","published":"2016-12-20"},{"cvss_score":7.8,"headline":"Microsoft Excel Featheader Record Memory Corruption","id":"CVE-2009-3129","kev_date_added":"2022-03-03","published":"2009-11-11"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2008-0081","kev_date_added":null,"published":"2008-01-16"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2015-6040","kev_date_added":null,"published":"2015-12-09"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2015-6122","kev_date_added":null,"published":"2015-12-09"}],"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":"2026-08-10","vendors":["Microsoft"]},"summary":"An unauthorized attacker can perform local spoofing in Microsoft Office due to improper access control, requiring a security patch.","url":"https://insights.sbomify.com/CVE-2026-42832/"}
