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-2026-62873 in the wild and no public exploit code.\n\nAffected product: Microsoft 365 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-2026-62873/ (Markdown: https://insights.sbomify.com/CVE-2026-62873/index.md)","id":"CVE-2026-62873","markdown":"https://insights.sbomify.com/CVE-2026-62873/index.md","name":"CVE-2026-62873","record":{"aliases":["GHSA-c89r-fxpx-x3w6"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft 365 Admin Center","requires_auth":"none","summary":"An attacker can elevate privileges in Microsoft 365 Admin Center by exploiting improper cryptographic signature verification.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_admin_center","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-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Improper verification of cryptographic signature in Microsoft 365 Admin Center allows an unauthorized attacker to elevate privileges 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 365 Admin Center Elevation of Privilege Vulnerability","id":"CVE-2026-62873","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Azure Billing Elevation of Privilege Vulnerability","id":"CVE-2026-62874"},"packages":[],"prev":{"headline":".NET Framework Elevation of Privilege Vulnerability","id":"CVE-2026-62872"},"products":["Microsoft 365 Admin Center"],"published":"2026-08-06","related":[{"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":"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 attacker can elevate privileges in Microsoft 365 Admin Center by exploiting improper cryptographic signature verification.","url":"https://insights.sbomify.com/CVE-2026-62873/"}
