An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-21343 and fix it if it is affected.\n\nWhat it is: CVE-2025-21343 is a high-severity vulnerability in Microsoft Windows 11 22h2, published on 14 Jan 2025. 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-2025-21343 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 11 22h2. 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-2025-21343/ (Markdown: https://insights.sbomify.com/CVE-2025-21343/index.md)","id":"CVE-2025-21343","markdown":"https://insights.sbomify.com/CVE-2025-21343/index.md","name":"CVE-2025-21343","record":{"aliases":["GHSA-rrm6-257m-2hgw"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows OS","requires_auth":"none","summary":"An attacker can exploit the Windows Web Threat Defense User Service to disclose sensitive information, requiring a security patch.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_11_22h2","vendor":"microsoft"},{"product":"windows_11_23h2","vendor":"microsoft"},{"product":"windows_11_24h2","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Windows Web Threat Defense User Service Information Disclosure 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 Web Threat Defense User Service Information Disclosure Vulnerability","id":"CVE-2025-21343","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_11_22h2","products":["microsoft:windows_11_22h2","microsoft:windows_11_23h2","microsoft:windows_11_24h2"],"type":"information_disclosure","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2025-21344"},"packages":[],"prev":{"headline":"Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability","id":"CVE-2025-21342"},"products":["Windows 11 Version 23H2","Windows 11 Version 24H2","Windows 11 version 22H2","Windows 11 version 22H3"],"published":"2025-01-14","related":[{"cvss_score":8.8,"headline":"Windows Hyper-V Remote Code Execution Vulnerability","id":"CVE-2024-49117","kev_date_added":null,"published":"2024-12-10"},{"cvss_score":8.8,"headline":"Windows OLE Remote Code Execution Vulnerability","id":"CVE-2024-21435","kev_date_added":null,"published":"2024-03-12"},{"cvss_score":8.4,"headline":"Windows Subsystem for Linux (WSL2) Kernel Remote Code Execution Vulnerability","id":"CVE-2025-24084","kev_date_added":null,"published":"2025-03-11"},{"cvss_score":8.1,"headline":"Remote Desktop Spoofing Vulnerability","id":"CVE-2025-33054","kev_date_added":null,"published":"2025-07-08"},{"cvss_score":8.1,"headline":"Windows Schannel Remote Code Execution Vulnerability","id":"CVE-2025-29828","kev_date_added":null,"published":"2025-06-10"},{"cvss_score":8.1,"headline":"Microsoft Windows VMSwitch Elevation of Privilege Vulnerability","id":"CVE-2024-43625","kev_date_added":null,"published":"2024-11-12"},{"cvss_score":8,"headline":"Secure Boot Security Feature Bypass Vulnerability","id":"CVE-2024-37978","kev_date_added":null,"published":"2024-07-09"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-06-09","vendors":["Microsoft"]},"summary":"An attacker can exploit the Windows Web Threat Defense User Service to disclose sensitive information, requiring a security patch.","url":"https://insights.sbomify.com/CVE-2025-21343/"}
