Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27066 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Admin Center. 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-2021-27066/ (Markdown: https://insights.sbomify.com/CVE-2021-27066/index.md)","id":"CVE-2021-27066","markdown":"https://insights.sbomify.com/CVE-2021-27066/index.md","name":"CVE-2021-27066","record":{"aliases":["GHSA-x3x8-r6pj-f993"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Admin Center","requires_auth":"low_privilege","summary":"An attacker can bypass security features in Windows Admin Center, potentially undermining protection mechanisms.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_admin_center","vendor":"microsoft"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Windows Admin Center Security Feature Bypass Vulnerability","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 Admin Center Security Feature Bypass Vulnerability","id":"CVE-2021-27066","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Azure DevOps Server and Team Foundation Server Information Disclosure Vulnerability","id":"CVE-2021-27067"},"packages":[],"prev":{"headline":"Microsoft Exchange Server Remote Code Execution","id":"CVE-2021-27065"},"products":["Windows Admin Center"],"published":"2021-03-11","related":[{"cvss_score":9.8,"headline":"Microsoft 365 Admin Center Elevation of Privilege Vulnerability","id":"CVE-2026-62873","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":9.8,"headline":"Privilege escalation in Windows Admin Center","id":"CVE-2019-0813","kev_date_added":null,"published":"2019-04-09"},{"cvss_score":8.8,"headline":"Windows Admin Center (WAC) Remote Code Execution Vulnerability","id":"CVE-2026-56196","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":8.8,"headline":"Windows Admin Center (WAC) Remote Code Execution Vulnerability","id":"CVE-2026-56197","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":8.8,"headline":"Windows Admin Center in Azure Portal Elevation of Privilege Vulnerability","id":"CVE-2026-41086","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":8.8,"headline":"Windows Admin Center Elevation of Privilege Vulnerability","id":"CVE-2026-26119","kev_date_added":null,"published":"2026-02-17"},{"cvss_score":8.7,"headline":"Windows Admin Center Spoofing Vulnerability","id":"CVE-2023-29347","kev_date_added":null,"published":"2023-07-11"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Microsoft"]},"summary":"An attacker can bypass security features in Windows Admin Center, potentially undermining protection mechanisms.","url":"https://insights.sbomify.com/CVE-2021-27066/"}
