Description
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.
