It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-50428 and fix it if it is affected.\n\nWhat it is: CVE-2026-50428 is a high-severity vulnerability in Microsoft Windows 11 26h1, published on 14 Jul 2026. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50428 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 11 26h1. 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-2026-50428/ (Markdown: https://insights.sbomify.com/CVE-2026-50428/index.md)","id":"CVE-2026-50428","markdown":"https://insights.sbomify.com/CVE-2026-50428/index.md","name":"CVE-2026-50428","record":{"aliases":["GHSA-v4hp-j4fc-x9fp"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows container driver","requires_auth":"low_privilege","summary":"An authorized local attacker can exploit an out-of-bounds read in the Windows container isolation driver to disclose sensitive information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_11_26h1","vendor":"microsoft"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Out-of-bounds read in Windows Container Isolation FS Filter Driver (unionfs.sys) allows an authorized attacker to disclose information locally.","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 Container Isolation FS Filter Driver (unionfs.sys) Information Disclosure Vulnerability","id":"CVE-2026-50428","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_11_26h1","products":["microsoft:windows_11_26h1"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Kernel Information Disclosure Vulnerability","id":"CVE-2026-50429"},"packages":[],"prev":{"headline":"Content Delivery Manager Elevation of Privilege Vulnerability","id":"CVE-2026-50427"},"products":["Windows 11 version 26H1"],"published":"2026-07-14","related":[{"cvss_score":8.2,"headline":"Windows Secure Kernel Mode Elevation of Privilege Vulnerability","id":"CVE-2026-85921","kev_date_added":null,"published":"2026-09-14"},{"cvss_score":8.2,"headline":"Windows Secure Kernel Mode Elevation of Privilege Vulnerability","id":"CVE-2026-83939","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.1,"headline":"Windows Schannel Remote Code Execution Vulnerability","id":"CVE-2026-105005","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":7.8,"headline":"Windows Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-85850","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":7.8,"headline":"Windows Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-97803","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":7.8,"headline":"Windows SMB Client Elevation of Privilege Vulnerability","id":"CVE-2026-69544","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":7.8,"headline":"Windows Container Isolation FS Filter Driver (unionfs.sys) Elevation of Privilege Vulnerability","id":"CVE-2026-62772","kev_date_added":null,"published":"2026-08-11"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Microsoft"]},"summary":"An authorized local attacker can exploit an out-of-bounds read in the Windows container isolation driver to disclose sensitive information.","url":"https://insights.sbomify.com/CVE-2026-50428/"}
