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-2026-42901 in the wild and no public exploit code.\n\nAffected product: Microsoft Entra. 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-2026-42901/ (Markdown: https://insights.sbomify.com/CVE-2026-42901/index.md)","id":"CVE-2026-42901","markdown":"https://insights.sbomify.com/CVE-2026-42901/index.md","name":"CVE-2026-42901","record":{"aliases":["GHSA-2jpj-7p7q-hfqj"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Entra ID","requires_auth":"none","summary":"An origin validation error in Microsoft Entra ID allows attackers to elevate privileges over the network, requiring immediate patching.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"entra_id","vendor":"microsoft"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"Origin validation error in Microsoft Entra ID 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 Entra ID Elevation of Privilege Vulnerability","id":"CVE-2026-42901","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft PowerToys Elevation of Privilege Vulnerability","id":"CVE-2026-42902"},"packages":[],"prev":{"headline":"Microsoft Windows App Store Elevation of Privilege Vulnerability","id":"CVE-2026-42900"},"products":["Microsoft Entra"],"published":"2026-05-22","related":[{"cvss_score":10,"headline":"Microsoft Entra ID Remote Code Execution Vulnerability","id":"CVE-2026-69836","kev_date_added":null,"published":"2026-08-20"},{"cvss_score":10,"headline":"Microsoft Entra ID Entitlement Management Spoofing Vulnerability","id":"CVE-2026-35431","kev_date_added":null,"published":"2026-04-23"},{"cvss_score":10,"headline":"Azure Entra ID Elevation of Privilege Vulnerability","id":"CVE-2025-55241","kev_date_added":null,"published":"2025-09-04"},{"cvss_score":9.9,"headline":"Entra ID Elevation of Privilege Vulnerability","id":"CVE-2026-83941","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":9.9,"headline":"Microsoft Entra ID Elevation of Privilege Vulnerability","id":"CVE-2026-69851","kev_date_added":null,"published":"2026-08-20"},{"cvss_score":9.8,"headline":"Azure Entra ID Elevation of Privilege Vulnerability","id":"CVE-2025-59246","kev_date_added":null,"published":"2025-10-09"}],"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":"2026-08-10","vendors":["Microsoft"]},"summary":"An origin validation error in Microsoft Entra ID allows attackers to elevate privileges over the network, requiring immediate patching.","url":"https://insights.sbomify.com/CVE-2026-42901/"}
