An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-81955 and fix it if it is affected.\n\nWhat it is: CVE-2026-81955 is a high-severity memory corruption vulnerability in Microsoft 365 Apps for Enterprise, published on 8 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-81955 in the wild and no public exploit code.\n\nAffected product: Microsoft 365 Apps for Enterprise. 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-2026-81955/ (Markdown: https://insights.sbomify.com/CVE-2026-81955/index.md)","id":"CVE-2026-81955","markdown":"https://insights.sbomify.com/CVE-2026-81955/index.md","name":"CVE-2026-81955","record":{"aliases":["GHSA-g5v3-7q65-84f8"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Graphics Component","requires_auth":"none","summary":"An unauthorized attacker can execute arbitrary code over the network via a heap-based buffer overflow in the Windows Graphics Component.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow in Microsoft Graphics Component allows an unauthorized attacker to execute code over a network.","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":"Windows Graphics Component Remote Code Execution Vulnerability","id":"CVE-2026-81955","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Excel Remote Code Execution Vulnerability","id":"CVE-2026-81956"},"packages":[],"prev":{"headline":"Microsoft Excel Remote Code Execution Vulnerability","id":"CVE-2026-81954"},"products":["Microsoft 365 Apps for Enterprise","Microsoft Office 2016","Microsoft Office 2019","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","Windows 10 Version 1607","Windows 10 Version 1809","Windows 10 Version 21H2","Windows 10 Version 22H2","Windows 11 Version 23H2","Windows 11 Version 24H2","Windows 11 Version 25H2","Windows 11 version 23H2","Windows 11 version 26H1","Windows Server 2012","Windows Server 2012 (Server Core installation)","Windows Server 2012 R2","Windows Server 2012 R2 (Server Core installation)","Windows Server 2016","Windows Server 2016 (Server Core installation)","Windows Server 2019","Windows Server 2019 (Server Core installation)","Windows Server 2022","Windows Server 2025","Windows Server 2025 (Server Core installation)"],"published":"2026-09-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-14","vendors":["Microsoft"]},"summary":"An unauthorized attacker can execute arbitrary code over the network via a heap-based buffer overflow in the Windows Graphics Component.","url":"https://insights.sbomify.com/CVE-2026-81955/"}
