An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-84012 and fix it if it is affected.\n\nWhat it is: CVE-2026-84012 is a high-severity use after free vulnerability in Microsoft Windows 10 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-2026-84012 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10 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-2026-84012/ (Markdown: https://insights.sbomify.com/CVE-2026-84012/index.md)","id":"CVE-2026-84012","markdown":"https://insights.sbomify.com/CVE-2026-84012/index.md","name":"CVE-2026-84012","record":{"aliases":["GHSA-8r59-4g6g-hvpm"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Remote Desktop","requires_auth":"none","summary":"An unauthorized attacker can execute arbitrary code over the network via a double free vulnerability in the Windows Remote Desktop Gateway Service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1607","vendor":"microsoft"},{"product":"windows_10_1809","vendor":"microsoft"},{"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":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"Double free in Remote Desktop Gateway Service 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 Remote Desktop Services Remote Code Execution Vulnerability","id":"CVE-2026-84012","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10_1607","products":["microsoft:windows_10_1607","microsoft:windows_10_1809","microsoft:windows_server_2012","microsoft:windows_server_2016","microsoft:windows_server_2019","microsoft:windows_server_2022","microsoft:windows_server_2025"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Telephony Server Elevation of Privilege Vulnerability","id":"CVE-2026-84013"},"packages":[],"prev":{"headline":"Windows SMB Client Security Feature Bypass Vulnerability","id":"CVE-2026-84011"},"products":["Windows 10 Version 1607","Windows 10 Version 1809","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":[{"cvss_score":9.8,"headline":"Microsoft Internet Key Exchange (IKE) Service Extensions Double Free","id":"CVE-2026-33824","kev_date_added":"2026-08-18","published":"2026-04-14"},{"cvss_score":8.8,"headline":"Microsoft Windows Shell Protection Mechanism Failure","id":"CVE-2026-21510","kev_date_added":"2026-02-10","published":"2026-02-10"},{"cvss_score":8.8,"headline":"Microsoft MSHTML Framework Protection Mechanism Failure","id":"CVE-2026-21513","kev_date_added":"2026-02-10","published":"2026-02-10"},{"cvss_score":8.8,"headline":"Microsoft Windows Defender SmartScreen Security Feature Bypass","id":"CVE-2023-32049","kev_date_added":"2023-07-11","published":"2023-07-11"},{"cvss_score":8.4,"headline":"Microsoft Streaming Service Untrusted Pointer Dereference","id":"CVE-2023-29360","kev_date_added":"2024-02-29","published":"2023-06-13"},{"cvss_score":7.8,"headline":"Microsoft Windows Heap-Based Buffer Overflow","id":"CVE-2026-85880","kev_date_added":"2026-09-08","published":"2026-09-08"},{"cvss_score":7.8,"headline":"Microsoft Active Directory Federation Services Insufficient Granularity of Access Control Vulnerability","id":"CVE-2026-56155","kev_date_added":"2026-07-14","published":"2026-07-14"}],"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 unauthorized attacker can execute arbitrary code over the network via a double free vulnerability in the Windows Remote Desktop Gateway Service.","url":"https://insights.sbomify.com/CVE-2026-84012/"}
