It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-20805 in the wild since at least 13 Jan 2026.\n\nAffected product: Microsoft Windows 10 1607. 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-2026-20805/ (Markdown: https://insights.sbomify.com/CVE-2026-20805/index.md)","id":"CVE-2026-20805","markdown":"https://insights.sbomify.com/CVE-2026-20805/index.md","name":"CVE-2026-20805","record":{"aliases":["GHSA-2x3m-95pj-8pg6"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Desktop Window Manager","requires_auth":"low_privilege","summary":"An authorized local attacker can exploit a flaw in the Desktop Window Manager to disclose sensitive information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1607","vendor":"microsoft"},{"product":"windows_10_1809","vendor":"microsoft"},{"product":"windows_10_21h2","vendor":"microsoft"},{"product":"windows_10_22h2","vendor":"microsoft"},{"product":"windows_11_23h2","vendor":"microsoft"},{"product":"windows_11_24h2","vendor":"microsoft"},{"product":"windows_11_25h2","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_2022_23h2","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Exposure of sensitive information to an unauthorized actor in Desktop Windows Manager allows an authorized attacker to disclose information locally.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-01-14","github_poc":6,"max_poc_stars":92,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-10T11:28:38Z","kind":"github_poc","ref":"https://github.com/ZeroDayEvil/CVE-2026-20805-PoC","stars":92,"title":"🛡️ Official AI Security Tool module for CVE-2026-20805 (Desktop Window Manager / dwm.exe Information Disclosure \u0026 Memory Leak Diagnostic)."},{"date":"2026-01-14T13:26:26Z","kind":"github_poc","ref":"https://github.com/fevar54/CVE-2026-20805-POC","stars":7,"title":"PoC de CVE-2026-20805: divulgacion de informacion en Desktop Window Manager (dwm.exe) de Windows."},{"date":"2026-01-19T19:16:25Z","kind":"github_poc","ref":"https://github.com/Uzair-Baig0900/CVE-2026-20805-PoC","stars":2,"title":"The PoC of information disclosure in Microsoft Desktop Windows Management."},{"date":"2026-01-31T06:40:56Z","kind":"github_poc","ref":"https://github.com/SimoesCTT/-SCTT-2026-33-0002-DWM-Visual-Field-Singularity","stars":1,"title":"### 📡 Theoretical Classification **ID:** SCTT-2026-33-0002   **Researcher:** Americo Simoes (SimoesCTT)   **Physics:** Theorem 4.2 - Turbulent Phase Transition (TPT)   **Constant:** α = 0.0302011   **Target:** Desktop Window Manager (dwm.exe) / Windows Graphics Component   **Obsoletes:** CVE-2026-20805 \u0026 CVE-2026-20871 (Visual-Latch Patches)"},{"date":"2026-01-28T03:50:36Z","kind":"github_poc","ref":"https://github.com/mrk336/Inside-CVE-2026-20805-How-a-Windows-DWM-Flaw-Exposed-Sensitive-Data","stars":0,"title":"CVE‑2026‑20805: A Windows Desktop Window Manager flaw causing local information disclosure.
