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-2026-23570 in the wild and no public exploit code.\n\nAffected product: TeamViewer DEX. 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-2026-23570/ (Markdown: https://insights.sbomify.com/CVE-2026-23570/index.md)","id":"CVE-2026-23570","markdown":"https://insights.sbomify.com/CVE-2026-23570/index.md","name":"CVE-2026-23570","record":{"aliases":["GHSA-wgvc-4m87-rq27"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TeamViewer DEX Client","requires_auth":"none","summary":"An adjacent network attacker can tamper with log timestamps in TeamViewer DEX Client, compromising log integrity and forensic correlation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TV","cpe":[{"product":"digital_employee_experience","vendor":"teamviewer"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A missing validation of a user-controlled value in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an adjacent network attacker to tamper with log timestamps via crafted UDP Sync command.
