It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2020-16928 and fix it if it is affected.\n\nWhat it is: CVE-2020-16928 is a high-severity vulnerability in Microsoft 365 Apps, published on 16 Oct 2020. 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-2020-16928 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-2020-16928/ (Markdown: https://insights.sbomify.com/CVE-2020-16928/index.md)","id":"CVE-2020-16928","markdown":"https://insights.sbomify.com/CVE-2020-16928/index.md","name":"CVE-2020-16928","record":{"aliases":["GHSA-3p6w-82x2-65rf"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Office","requires_auth":"none","summary":"An attacker can elevate privileges by convincing a user to open a specially crafted file in Microsoft Office Click-to-Run.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_apps","vendor":"microsoft"},{"product":"office","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":"\u003cp\u003eAn elevation of privilege vulnerability exists in the way that Microsoft Office Click-to-Run (C2R) AppVLP handles certain files.
