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-2026-56165 in the wild and no public exploit code.\n\nAffected product: Microsoft Account. 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-2026-56165/ (Markdown: https://insights.sbomify.com/CVE-2026-56165/index.md)","id":"CVE-2026-56165","markdown":"https://insights.sbomify.com/CVE-2026-56165/index.md","name":"CVE-2026-56165","record":{"aliases":["GHSA-w7fc-p5p7-c9pf"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Account","requires_auth":"none","summary":"An unauthorized attacker can execute code remotely via a heap-based buffer overflow in Microsoft Account services.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"account","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-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow in Microsoft Account 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 Account Remote Code Execution Vulnerability","id":"CVE-2026-56165","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Azure AI Search Elevation of Privilege Vulnerability","id":"CVE-2026-56167"},"packages":[],"prev":{"headline":"Microsoft SharePoint Server Missing Authentication for Critical Function","id":"CVE-2026-56164"},"products":["Microsoft Account"],"published":"2026-07-23","related":[{"cvss_score":9.3,"headline":"Microsoft Account Spoofing Vulnerability","id":"CVE-2026-21264","kev_date_added":null,"published":"2026-01-22"},{"cvss_score":8.2,"headline":"Microsoft Account Elevation of Privilege Vulnerability","id":"CVE-2025-21396","kev_date_added":null,"published":"2025-01-29"}],"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":"2026-10-28","vendors":["Microsoft"]},"summary":"An unauthorized attacker can execute code remotely via a heap-based buffer overflow in Microsoft Account services.","url":"https://insights.sbomify.com/CVE-2026-56165/"}
