CVE-2026-8381: TeamViewer Dex On-Premises

Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

A broken access control vulnerability exists in the TeamViewer DEX Platform (On‑Premises) prior version 9.2. Certain backend API endpoints do not correctly enforce authorization checks, allowing an authenticated user with low privileges to perform actions and access resources intended only for higher‑privileged roles. An attacker with low‑privileged credentials may exploit this to gain unauthorized access to administrative or sensitive functionality.
