It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-96997 and fix it if it is affected.\n\nWhat it is: CVE-2026-96997 is a high-severity use after free vulnerability in Microsoft 365 Apps, published on 13 Oct 2026. 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-2026-96997 in the wild and no public exploit code.\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-2026-96997/ (Markdown: https://insights.sbomify.com/CVE-2026-96997/index.md)","id":"CVE-2026-96997","markdown":"https://insights.sbomify.com/CVE-2026-96997/index.md","name":"CVE-2026-96997","record":{"aliases":["GHSA-5pr9-h96m-v7v2"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Office OneNote","requires_auth":"low_privilege","summary":"An authorized local attacker can exploit a use-after-free flaw in Microsoft Office OneNote to elevate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_apps","vendor":"microsoft"},{"product":"microsoft_365","vendor":"microsoft"},{"product":"office_2021","vendor":"microsoft"},{"product":"office_2024","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use after free in Microsoft Office OneNote allows an authorized attacker to elevate privileges 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 OneNote Elevation of Privilege Vulnerability","id":"CVE-2026-96997","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:365_apps","products":["microsoft:365_apps","microsoft:microsoft_365","microsoft:office_2021","microsoft:office_2024"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Office Word Remote Code Execution Vulnerability","id":"CVE-2026-97001"},"packages":[],"prev":{"headline":"Microsoft Office Word Remote Code Execution Vulnerability","id":"CVE-2026-96996"},"products":["Microsoft 365 Apps for Enterprise","Microsoft Office 365 for Mac","Microsoft Office LTSC 2021","Microsoft Office LTSC 2024","Microsoft Office LTSC for Mac 2021","Microsoft Office LTSC for Mac 2024"],"published":"2026-10-13","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"},{"cvss_score":7.8,"headline":"Microsoft Excel Security Feature Bypass","id":"CVE-2021-42292","kev_date_added":"2021-11-17","published":"2021-11-10"}],"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":"2026-10-29","vendors":["Microsoft"]},"summary":"An authorized local attacker can exploit a use-after-free flaw in Microsoft Office OneNote to elevate privileges.","url":"https://insights.sbomify.com/CVE-2026-96997/"}
