An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-83523 and fix it if it is affected.\n\nWhat it is: CVE-2026-83523 is a high-severity memory corruption vulnerability in Microsoft Windows 11 24h2, published on 13 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-83523 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 11 24h2. 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-2026-83523/ (Markdown: https://insights.sbomify.com/CVE-2026-83523/index.md)","id":"CVE-2026-83523","markdown":"https://insights.sbomify.com/CVE-2026-83523/index.md","name":"CVE-2026-83523","record":{"aliases":["GHSA-r544-2pm4-5734"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Image Acquisition","requires_auth":"none","summary":"Heap-based buffer overflow in Windows Image Acquisition allows remote attackers to execute arbitrary code without authentication.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_11_24h2","vendor":"microsoft"},{"product":"windows_11_25h2","vendor":"microsoft"},{"product":"windows_11_26h1","vendor":"microsoft"},{"product":"windows_11_26h2","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow in Windows Image Acquisition 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":"Windows Image Acquisition Remote Code Execution Vulnerability","id":"CVE-2026-83523","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_11_24h2","products":["microsoft:windows_11_24h2","microsoft:windows_11_25h2","microsoft:windows_11_26h1","microsoft:windows_11_26h2","microsoft:windows_server_2025"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"RedPort Optimizer wXa-223 System Clock datetime.php exec command injection","id":"CVE-2026-83524"},"packages":[],"prev":{"headline":"Windows IKE Extension Spoofing Vulnerability","id":"CVE-2026-83522"},"products":["Windows 11 Version 24H2","Windows 11 Version 25H2","Windows 11 Version 26H2","Windows 11 version 26H1","Windows Server 2025","Windows Server 2025 (Server Core installation)"],"published":"2026-10-13","related":[{"cvss_score":7.8,"headline":"Microsoft Windows Link Following","id":"CVE-2025-60710","kev_date_added":"2026-04-13","published":"2025-11-11"},{"cvss_score":9.8,"headline":"Remote Desktop Client Remote Code Execution Vulnerability","id":"CVE-2026-54990","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":9.8,"headline":"Windows Graphics Component Remote Code Execution Vulnerability","id":"CVE-2025-50165","kev_date_added":null,"published":"2025-08-12"},{"cvss_score":9.8,"headline":"Windows NTLM V1 Elevation of Privilege Vulnerability","id":"CVE-2025-21311","kev_date_added":null,"published":"2025-01-14"},{"cvss_score":8.8,"headline":"Windows SmartScreen Security Feature Bypass Vulnerability","id":"CVE-2026-108463","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Microsoft Windows Media Foundation Remote Code Execution Vulnerability","id":"CVE-2026-62744","kev_date_added":null,"published":"2026-09-08"}],"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":"2026-10-29","vendors":["Microsoft"]},"summary":"Heap-based buffer overflow in Windows Image Acquisition allows remote attackers to execute arbitrary code without authentication.","url":"https://insights.sbomify.com/CVE-2026-83523/"}
