An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-73010 and fix it if it is affected.\n\nWhat it is: CVE-2026-73010 is a critical use after free vulnerability in Microsoft Windows 10 1809, published on 8 Sep 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-2026-73010 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10 1809. 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-2026-73010/ (Markdown: https://insights.sbomify.com/CVE-2026-73010/index.md)","id":"CVE-2026-73010","markdown":"https://insights.sbomify.com/CVE-2026-73010/index.md","name":"CVE-2026-73010","record":{"aliases":["GHSA-275q-g846-p5mh"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Failover Cluster","requires_auth":"none","summary":"An unauthorized attacker can execute code over the network via a use-after-free flaw in Windows Failover Cluster.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1809","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use after free in Windows Failover Cluster 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":"Microsoft Failover Cluster Remote Code Execution Vulnerability","id":"CVE-2026-73010","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10_1809","products":["microsoft:windows_10_1809","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 Biometric Service Elevation of Privilege Vulnerability","id":"CVE-2026-73011"},"packages":[],"prev":{"headline":"Windows Secure Socket Tunneling Protocol (SSTP) Remote Code Execution Vulnerability","id":"CVE-2026-73009"},"products":["Windows 10 Version 1809","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":[{"cvss_score":8.8,"headline":"Microsoft SmartScreen Prompt Security Feature Bypass","id":"CVE-2024-29988","kev_date_added":"2024-04-30","published":"2024-04-09"},{"cvss_score":8.1,"headline":"Microsoft Windows Internet Shortcut Files Security Feature Bypass","id":"CVE-2024-21412","kev_date_added":"2024-02-13","published":"2024-02-13"},{"cvss_score":7.8,"headline":"Microsoft Windows Use After Free","id":"CVE-2025-62221","kev_date_added":"2025-12-09","published":"2025-12-09"},{"cvss_score":7.8,"headline":"Microsoft Windows DWM Core Library Use-After-Free","id":"CVE-2025-30400","kev_date_added":"2025-05-13","published":"2025-05-13"},{"cvss_score":7.8,"headline":"Microsoft Windows Kernel Exposed IOCTL with Insufficient Access Control","id":"CVE-2024-21338","kev_date_added":"2024-03-04","published":"2024-02-13"},{"cvss_score":7.8,"headline":"Microsoft Windows Desktop Window Manager (DWM) Core Library Privilege Escalation","id":"CVE-2023-36033","kev_date_added":"2023-11-14","published":"2023-11-14"},{"cvss_score":7.8,"headline":"Microsoft Streaming Service Proxy Privilege Escalation","id":"CVE-2023-36802","kev_date_added":"2023-09-12","published":"2023-09-12"}],"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":"total"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["Microsoft"]},"summary":"An unauthorized attacker can execute code over the network via a use-after-free flaw in Windows Failover Cluster.","url":"https://insights.sbomify.com/CVE-2026-73010/"}
