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-2026-19042 in the wild and no public exploit code.\n\nAffected product: TeamViewer Full Client. 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-2026-19042/ (Markdown: https://insights.sbomify.com/CVE-2026-19042/index.md)","id":"CVE-2026-19042","markdown":"https://insights.sbomify.com/CVE-2026-19042/index.md","name":"CVE-2026-19042","record":{"aliases":["GHSA-hv9x-3jwv-hvm4"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TeamViewer Linux Client","requires_auth":"none","summary":"Remote attackers can execute arbitrary commands via malicious chat links in TeamViewer Linux clients, requiring user interaction to click the link.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TV","cpe":[],"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","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A command injection vulnerability in TeamViewer Full\nClient and Host for Linux prior to version 15.81.5 allows a remote attacker to\nexecute arbitrary commands in the context of the current user via a specially\ncrafted URL sent through the out-of-session chat feature.
