An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-23563 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-2026-23563/ (Markdown: https://insights.sbomify.com/CVE-2026-23563/index.md)","id":"CVE-2026-23563","markdown":"https://insights.sbomify.com/CVE-2026-23563/index.md","name":"CVE-2026-23563","record":{"aliases":["GHSA-82cg-rxq8-hc7m"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"TeamViewer DEX client","requires_auth":"high_privilege","summary":"A local attacker can escalate privileges by deleting protected system files via a crafted symlink in TeamViewer DEX client.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TV","cpe":[{"product":"digital_employee_experience","vendor":"teamviewer"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Improper Link Resolution Before File Access (invoked by 1E‑Explorer‑TachyonCore‑DeleteFileByPath instruction) in TeamViewer DEX - 1E Client before version 26.1 on Windows allows a low‑privileged local attacker to delete protected system files via a crafted RPC control junction or symlink that is followed when the delete instruction executes.","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":"Privilege escalation in TeamViewer DEX via DeleteFileByPath instruction","id":"CVE-2026-23563","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Transmission of Unencrypted Data in Content Distribution Service","id":"CVE-2026-23564"},"packages":[],"prev":{"headline":"Multiple RBAC issues in XAPI","id":"CVE-2026-23562"},"products":["DEX"],"published":"2026-01-29","related":[{"cvss_score":8.8,"headline":"File Hash Validation Bypass in NomadBranch.exe","id":"CVE-2025-44016","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":7.2,"headline":"Command Injection in 1E-Explorer-TachyonCore-DevicesListeningOnAPort Instruction","id":"CVE-2025-64986","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":7.2,"headline":"Command Injection in 1E-Explorer-TachyonCore-CheckSimpleIoC Instruction","id":"CVE-2025-64987","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":7.2,"headline":"Command Injection in 1E-Nomad-GetCmContentLocations Instruction","id":"CVE-2025-64988","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":7.2,"headline":"Command Injection in 1E-Explorer-TachyonCore-FindFileBySizeAndHash Instruction","id":"CVE-2025-64989","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":6.8,"headline":"Command Injection in 1E-Nomad-RunPkgStatusRequest Instruction in TeamViewer DEX","id":"CVE-2026-23571","kev_date_added":null,"published":"2026-01-29"},{"cvss_score":6.8,"headline":"Command Injection in 1E-Explorer-TachyonCore-LogoffUser Instruction","id":"CVE-2025-64990","kev_date_added":null,"published":"2025-12-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-01-29","vendors":["TeamViewer"]},"summary":"A local attacker can escalate privileges by deleting protected system files via a crafted symlink in TeamViewer DEX client.","url":"https://insights.sbomify.com/CVE-2026-23563/"}
