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: Yes. Attackers have exploited CVE-2021-42292 in the wild since at least 17 Nov 2021.\n\nAffected product: Microsoft 365 Apps. 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-2021-42292/ (Markdown: https://insights.sbomify.com/CVE-2021-42292/index.md)","id":"CVE-2021-42292","markdown":"https://insights.sbomify.com/CVE-2021-42292/index.md","name":"CVE-2021-42292","record":{"aliases":["GHSA-jp63-fcqh-36rc"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Excel","requires_auth":"none","summary":"Attackers can bypass security features in Microsoft Excel, potentially exposing users to further threats.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_apps","vendor":"microsoft"},{"product":"excel","vendor":"microsoft"},{"product":"office","vendor":"microsoft"},{"product":"office_2016","vendor":"microsoft"},{"product":"office_2019","vendor":"microsoft"},{"product":"office_2021","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Microsoft Excel Security Feature Bypass Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-11-09","github_poc":1,"max_poc_stars":19,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-11-09T12:14:45Z","kind":"github_poc","ref":"https://github.com/corelight/CVE-2021-42292","stars":19,"title":"A Zeek package to detect CVE-2021-42292, a Microsoft Excel local privilege escalation exploit."}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Excel Security Feature Bypass","id":"CVE-2021-42292","indexable":true,"kev":{"dateAdded":"2021-11-17","dueDate":"2021-12-01","knownRansomwareCampaignUse":"Unknown","product":"Office","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Excel Security Feature Bypass"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:365_apps","products":["microsoft:365_apps","microsoft:excel","microsoft:office","microsoft:office_2016","microsoft:office_2019","microsoft:office_2021"],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Jet Red Database Engine and Access Connectivity Engine Elevation of Privilege Vulnerability","id":"CVE-2021-42293"},"packages":[],"prev":{"headline":"Active Directory Domain Services Elevation of Privilege Vulnerability","id":"CVE-2021-42291"},"products":["Microsoft 365 Apps for Enterprise","Microsoft Excel 2013 Service Pack 1","Microsoft Excel 2016","Microsoft Office 2013 Service Pack 1","Microsoft Office 2016","Microsoft Office 2019","Microsoft Office 2019 for Mac","Microsoft Office LTSC 2021","Microsoft Office LTSC for Mac 2021"],"published":"2021-11-10","related":[{"cvss_score":9.8,"headline":"Microsoft Outlook Improper Input Validation","id":"CVE-2024-21413","kev_date_added":"2025-02-06","published":"2024-02-13"},{"cvss_score":9.8,"headline":"Microsoft Office Outlook Privilege Escalation","id":"CVE-2023-23397","kev_date_added":"2023-03-14","published":"2023-03-14"},{"cvss_score":8.8,"headline":"Microsoft Project Remote Code Execution Vulnerability","id":"CVE-2024-38189","kev_date_added":"2024-08-13","published":"2024-08-13"},{"cvss_score":8.8,"headline":"Microsoft Outlook Security Feature Bypass","id":"CVE-2023-35311","kev_date_added":"2023-07-11","published":"2023-07-11"},{"cvss_score":7.8,"headline":"Microsoft Office Word Reliance on Untrusted Inputs in a Security Decision","id":"CVE-2026-21514","kev_date_added":"2026-02-10","published":"2026-02-10"},{"cvss_score":7.8,"headline":"Microsoft Office Security Feature Bypass","id":"CVE-2026-21509","kev_date_added":"2026-01-26","published":"2026-01-26"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Microsoft"]},"summary":"Attackers can bypass security features in Microsoft Excel, potentially exposing users to further threats.","url":"https://insights.sbomify.com/CVE-2021-42292/"}
