An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-108131 and fix it if it is affected.\n\nWhat it is: CVE-2026-108131 is a high-severity vulnerability in Microsoft Windows 10 Version 1607, published on 13 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-108131 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10 Version 1607. 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-2026-108131/ (Markdown: https://insights.sbomify.com/CVE-2026-108131/index.md)","id":"CVE-2026-108131","markdown":"https://insights.sbomify.com/CVE-2026-108131/index.md","name":"CVE-2026-108131","record":{"aliases":["GHSA-fhqq-2fpf-qcf9"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows AD FS","requires_auth":"none","summary":"An unauthorized attacker can perform spoofing attacks against Active Directory Federation Services, requiring immediate patching by Windows administrators.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"},{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"No cwe for this issue in Active Directory Federation Services (AD FS) allows an unauthorized attacker to perform spoofing 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":"Active Directory Federation Services (AD FS) Spoofing Vulnerability","id":"CVE-2026-108131","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Kerberos Elevation of Privilege Vulnerability","id":"CVE-2026-108132"},"packages":[],"prev":{"headline":"Windows Virtualization-Based Security (VBS) Enclave Elevation of Privilege Vulnerability","id":"CVE-2026-108130"},"products":["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 26H2","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":"2026-10-13","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Microsoft"]},"summary":"An unauthorized attacker can perform spoofing attacks against Active Directory Federation Services, requiring immediate patching by Windows administrators.","url":"https://insights.sbomify.com/CVE-2026-108131/"}
