An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-94520 in the wild and no public exploit code.\n\nAffected product: Microsoft SQL Server 2017 (GDR). 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-2026-94520/ (Markdown: https://insights.sbomify.com/CVE-2026-94520/index.md)","id":"CVE-2026-94520","markdown":"https://insights.sbomify.com/CVE-2026-94520/index.md","name":"CVE-2026-94520","record":{"aliases":["GHSA-vxwq-jqhm-w2r6"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft SQL Server","requires_auth":"high_privilege","summary":"An authorized attacker can cause a denial of service in Microsoft SQL Server by exploiting a format string vulnerability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"Use of externally-controlled format string in SQL Server allows an authorized 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":"Microsoft SQL Server Denial of Service Vulnerability","id":"CVE-2026-94520","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"lamp-cloud through 5.10.0 Unauthorized User Profile Access via getUserInfoById","id":"CVE-2026-94532"},"packages":[],"prev":{"headline":"SQL Server Remote Code Execution Vulnerability","id":"CVE-2026-94512"},"products":["Microsoft SQL Server 2017 (GDR)","Microsoft SQL Server 2017 for x64-based Systems (CU31)","Microsoft SQL Server 2019 (GDR)","Microsoft SQL Server 2019 for x64-based Systems (CU32)","Microsoft SQL Server 2022 (GDR)","Microsoft SQL Server 2022 for x64-based Systems (CU27)","Microsoft SQL Server 2025 for x64-based Systems (CU9)","Microsoft SQL Server 2025 for x64-based Systems (GDR)"],"published":"2026-10-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Microsoft"]},"summary":"An authorized attacker can cause a denial of service in Microsoft SQL Server by exploiting a format string vulnerability.","url":"https://insights.sbomify.com/CVE-2026-94520/"}
