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-2025-21355 in the wild and no public exploit code.\n\nAffected product: Microsoft Bing. 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-2025-21355/ (Markdown: https://insights.sbomify.com/CVE-2025-21355/index.md)","id":"CVE-2025-21355","markdown":"https://insights.sbomify.com/CVE-2025-21355/index.md","name":"CVE-2025-21355","record":{"aliases":["GHSA-fx4j-9fqf-p9p2"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Bing","requires_auth":"none","summary":"An unauthorized attacker can execute code on Microsoft Bing due to missing authentication for a critical function.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"bing","vendor":"microsoft"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Missing Authentication for Critical Function in Microsoft Bing 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 Bing Remote Code Execution Vulnerability","id":"CVE-2025-21355","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Office Visio Remote Code Execution Vulnerability","id":"CVE-2025-21356"},"packages":[],"prev":{"headline":"Microsoft Excel Remote Code Execution Vulnerability","id":"CVE-2025-21354"},"products":["Microsoft Bing"],"published":"2025-02-19","related":[{"cvss_score":10,"headline":"Microsoft Bing Remote Code Execution Vulnerability","id":"CVE-2026-33819","kev_date_added":null,"published":"2026-04-23"},{"cvss_score":10,"headline":"Microsoft Bing Elevation of Privilege Vulnerability","id":"CVE-2026-32186","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":6.8,"headline":"Code injection in n/a","id":"CVE-2014-1670","kev_date_added":null,"published":"2014-01-25"},{"cvss_score":6.5,"headline":"Microsoft Bing Tampering Vulnerability","id":"CVE-2026-26120","kev_date_added":null,"published":"2026-03-19"},{"cvss_score":6.5,"headline":"Cross-site scripting in Microsoft Bing Search for Android","id":"CVE-2020-1329","kev_date_added":null,"published":"2020-06-09"},{"cvss_score":4.7,"headline":"Microsoft Bing Search Spoofing Vulnerability","id":"CVE-2021-33753","kev_date_added":null,"published":"2021-07-14"}],"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":"2026-02-13","vendors":["Microsoft"]},"summary":"An unauthorized attacker can execute code on Microsoft Bing due to missing authentication for a critical function.","url":"https://insights.sbomify.com/CVE-2025-21355/"}
