Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-58626 and fix it if it is affected.\n\nWhat it is: CVE-2026-58626 is a high-severity use after free vulnerability in Microsoft Windows 10 21h2, published on 14 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-58626 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10 21h2. 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-2026-58626/ (Markdown: https://insights.sbomify.com/CVE-2026-58626/index.md)","id":"CVE-2026-58626","markdown":"https://insights.sbomify.com/CVE-2026-58626/index.md","name":"CVE-2026-58626","record":{"aliases":["GHSA-h9cr-8qw2-fhg7"],"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":"low_privilege","summary":"An authorized attacker can execute arbitrary code over the network via a use-after-free flaw in Windows Remote Desktop Services.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_21h2","vendor":"microsoft"},{"product":"windows_10_22h2","vendor":"microsoft"},{"product":"windows_11_24h2","vendor":"microsoft"},{"product":"windows_11_25h2","vendor":"microsoft"},{"product":"windows_11_26h1","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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 Remote Desktop Services allows an authorized 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-2026-58626","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10_21h2","products":["microsoft:windows_10_21h2","microsoft:windows_10_22h2","microsoft:windows_11_24h2","microsoft:windows_11_25h2","microsoft:windows_11_26h1","microsoft:windows_server_2022","microsoft:windows_server_2025"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows DHCP Server Denial of Service Vulnerability","id":"CVE-2026-58627"},"packages":[],"prev":{"headline":"Apache MINA SSHD: Remote execution of JGit commands can write files on the server","id":"CVE-2026-58624"},"products":["Windows 10 Version 21H2","Windows 10 Version 22H2","Windows 11 Version 24H2","Windows 11 Version 25H2","Windows 11 version 26H1","Windows Server 2022","Windows Server 2025","Windows Server 2025 (Server Core installation)"],"published":"2026-07-14","related":[{"cvss_score":7.8,"headline":"Microsoft Windows Hyper-V NT Kernel Integration VSP Heap-based Buffer Overflow","id":"CVE-2025-21333","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":7.8,"headline":"Microsoft Windows Hyper-V NT Kernel Integration VSP Use-After-Free","id":"CVE-2025-21334","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":7.8,"headline":"Microsoft Windows Hyper-V NT Kernel Integration VSP Use-After-Free","id":"CVE-2025-21335","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":9.6,"headline":"Windows TCP/IP Elevation of Privilege Vulnerability","id":"CVE-2026-42904","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":8.8,"headline":"Windows Hyper-V Remote Code Execution Vulnerability","id":"CVE-2026-105733","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Windows AppX Deployment Extensions Elevation of Privilege Vulnerability","id":"CVE-2026-69945","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Windows Graphics Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-88073","kev_date_added":null,"published":"2026-10-13"}],"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":"2026-10-28","vendors":["Microsoft"]},"summary":"An authorized attacker can execute arbitrary code over the network via a use-after-free flaw in Windows Remote Desktop Services.","url":"https://insights.sbomify.com/CVE-2026-58626/"}
