An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-12703 in the wild and no public exploit code.\n\nAffected product: TeamViewer ONE. 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-2026-12703/ (Markdown: https://insights.sbomify.com/CVE-2026-12703/index.md)","id":"CVE-2026-12703","markdown":"https://insights.sbomify.com/CVE-2026-12703/index.md","name":"CVE-2026-12703","record":{"aliases":["GHSA-r926-cxpx-jff4"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"TeamViewer macOS client","requires_auth":"high_privilege","summary":"An authenticated attacker can bypass 2FA to establish remote connections on TeamViewer for macOS hosts.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TV","cpe":[],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"TeamViewer Full Client and Host for macOS before version 15.80 contain a business logic error that can allow an authenticated attacker to bypass a configured 2FA for Connections approval flow via Unattended Access and establish a remote connection to an affected macOS host.","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":"Bypass of 2FA for Connections via Unattended Access in TeamViewer for macOS","id":"CVE-2026-12703","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"SAML assertion replay via skipped InResponseTo validation","id":"CVE-2026-12704"},"packages":[],"prev":{"headline":"Missing authorization in Octopus Server","id":"CVE-2026-12702"},"products":["ONE","Remote","Tensor"],"published":"2026-07-29","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-07-29","vendors":["TeamViewer"]},"summary":"An authenticated attacker can bypass 2FA to establish remote connections on TeamViewer for macOS hosts.","url":"https://insights.sbomify.com/CVE-2026-12703/"}
