An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-85321 and fix it if it is affected.\n\nWhat it is: CVE-2026-85321 is a high-severity denial of service vulnerability in Microsoft Windows Server 2012, 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-2026-85321 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Server 2012. 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-2026-85321/ (Markdown: https://insights.sbomify.com/CVE-2026-85321/index.md)","id":"CVE-2026-85321","markdown":"https://insights.sbomify.com/CVE-2026-85321/index.md","name":"CVE-2026-85321","record":{"aliases":["GHSA-6qx8-6vhq-mgfc"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Active Directory Federation Services","requires_auth":"none","summary":"An unauthorized attacker can cause a denial of service in Active Directory Federation Services by exploiting resource allocation limits.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"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:N/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Allocation of resources without limits or throttling in Active Directory Federation Services (AD FS) allows an unauthorized attacker to deny service 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) Denial of Service Vulnerability","id":"CVE-2026-85321","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_server_2012","products":["microsoft:windows_server_2012","microsoft:windows_server_2016","microsoft:windows_server_2019","microsoft:windows_server_2022","microsoft:windows_server_2025"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Routing and Remote Access Service (RRAS) Information Disclosure Vulnerability","id":"CVE-2026-85322"},"packages":[],"prev":{"headline":"Windows Print Spooler Components Information Disclosure Vulnerability","id":"CVE-2026-85320"},"products":["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":[{"cvss_score":9.8,"headline":"Microsoft Windows Server Update Service (WSUS) Deserialization of Untrusted Data","id":"CVE-2025-59287","kev_date_added":"2025-10-24","published":"2025-10-14"},{"cvss_score":9.8,"headline":"Windows Services for NFS ONCRPC XDR Driver Remote Code Execution Vulnerability","id":"CVE-2026-69595","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":9.8,"headline":"Windows Services for NFS ONCRPC XDR Driver Remote Code Execution Vulnerability","id":"CVE-2026-78445","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":9.8,"headline":"Windows Netlogon Remote Code Execution Vulnerability","id":"CVE-2026-41089","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9.8,"headline":"Windows KDC Proxy Remote Code Execution Vulnerability","id":"CVE-2024-43639","kev_date_added":null,"published":"2024-11-12"},{"cvss_score":9.8,"headline":"Windows Network File System Remote Code Execution Vulnerability","id":"CVE-2023-24941","kev_date_added":null,"published":"2023-05-09"},{"cvss_score":9.8,"headline":"Windows Network File System Remote Code Execution Vulnerability","id":"CVE-2022-30136","kev_date_added":null,"published":"2022-06-15"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Microsoft"]},"summary":"An unauthorized attacker can cause a denial of service in Active Directory Federation Services by exploiting resource allocation limits.","url":"https://insights.sbomify.com/CVE-2026-85321/"}
