Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45648 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Server 2022. 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-2026-45648/ (Markdown: https://insights.sbomify.com/CVE-2026-45648/index.md)","id":"CVE-2026-45648","markdown":"https://insights.sbomify.com/CVE-2026-45648/index.md","name":"CVE-2026-45648","record":{"aliases":["GHSA-gmq7-hvj8-4x66"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Server AD DS","requires_auth":"low_privilege","summary":"An authorized attacker can execute arbitrary code remotely via a stack-based buffer overflow in Windows Active Directory Domain Services.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"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-121","name":"Stack-based Buffer Overflow"}],"description":"Stack-based buffer overflow in Active Directory Domain 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 Active Directory Domain Services Remote Code Execution Vulnerability","id":"CVE-2026-45648","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_server_2022","products":["microsoft:windows_server_2022","microsoft:windows_server_2025"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Office for Android Spoofing Vulnerability","id":"CVE-2026-45649"},"packages":[],"prev":{"headline":"Microsoft Defender for Endpoint for Mac Elevation of Privilege Vulnerability","id":"CVE-2026-45647"},"products":["Windows Server 2022","Windows Server 2025","Windows Server 2025 (Server Core installation)"],"published":"2026-06-09","related":[{"cvss_score":9.8,"headline":"Windows Network File System Remote Code Execution Vulnerability","id":"CVE-2022-34715","kev_date_added":null,"published":"2022-08-09"},{"cvss_score":9.1,"headline":"Remote Desktop Spoofing Vulnerability","id":"CVE-2025-50171","kev_date_added":null,"published":"2025-08-12"},{"cvss_score":8.8,"headline":"Windows Domain Name Service Remote Code Execution Vulnerability","id":"CVE-2026-70167","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Windows Kernel Elevation of Privilege Vulnerability","id":"CVE-2024-30064","kev_date_added":null,"published":"2024-06-11"},{"cvss_score":8.1,"headline":"Windows DNS Server Remote Code Execution Vulnerability","id":"CVE-2026-69858","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.1,"headline":"Windows SMBv3 Server Remote Code Execution Vulnerability","id":"CVE-2024-43447","kev_date_added":null,"published":"2024-11-12"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["Microsoft"]},"summary":"An authorized attacker can execute arbitrary code remotely via a stack-based buffer overflow in Windows Active Directory Domain Services.","url":"https://insights.sbomify.com/CVE-2026-45648/"}
