Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-21381 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-2024-21381/ (Markdown: https://insights.sbomify.com/CVE-2024-21381/index.md)","id":"CVE-2024-21381","markdown":"https://insights.sbomify.com/CVE-2024-21381/index.md","name":"CVE-2024-21381","record":{"aliases":["GHSA-v87j-jxhf-9vq2"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Azure AD B2C","requires_auth":"low_privilege","summary":"Attackers can exploit a spoofing vulnerability in Azure AD B2C to bypass security controls, requiring a vendor patch.","user_interaction":"not_required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"azure_active_directory","vendor":"microsoft"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Microsoft Azure Active Directory B2C Spoofing 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":"Microsoft Azure Active Directory B2C Spoofing Vulnerability","id":"CVE-2024-21381","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Edge for Android Information Disclosure Vulnerability","id":"CVE-2024-21382"},"packages":[],"prev":{"headline":"Microsoft Dynamics Business Central/NAV Information Disclosure Vulnerability","id":"CVE-2024-21380"},"products":["Entra"],"published":"2024-02-13","related":[{"cvss_score":10,"headline":"Azure Active Directory Elevation of Privilege Vulnerability","id":"CVE-2026-45480","kev_date_added":null,"published":"2026-06-19"},{"cvss_score":9.9,"headline":"Azure Active Directory Elevation of Privilege Vulnerability","id":"CVE-2026-50481","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":8.1,"headline":"Azure Active Directory Information Disclosure Vulnerability","id":"CVE-2021-42306","kev_date_added":null,"published":"2021-11-24"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Microsoft"]},"summary":"Attackers can exploit a spoofing vulnerability in Azure AD B2C to bypass security controls, requiring a vendor patch.","url":"https://insights.sbomify.com/CVE-2024-21381/"}
