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-2026-16444 in the wild and no public exploit code.\n\nAffected product: TeamViewer Full Client, Host, QuickSupport \u0026 Portable. 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-2026-16444/ (Markdown: https://insights.sbomify.com/CVE-2026-16444/index.md)","id":"CVE-2026-16444","markdown":"https://insights.sbomify.com/CVE-2026-16444/index.md","name":"CVE-2026-16444","record":{"aliases":["GHSA-3mf4-g44r-xcvg"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"TeamViewer desktop client","requires_auth":"none","summary":"An authenticated remote session participant can write files to unintended locations via path traversal, potentially achieving arbitrary code execution.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TV","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"Improper\nneutralization of path traversal sequences in TeamViewer Desktop Clients prior\nVersion 15.81.5 allows an authenticated remote session participant to write files\nto unintended locations on the local file system via file transfer or virtual\nfile clipboard mechanisms.
