Missing server-side input validation leading to a command injection vulnerability was found and fixed in TeamViewer DEX Platform - On-Premises (formerly 1E DEX Platform).

2. Vulnerability details

CVE-ID

CVE-2026-2695

Description

A command injection vulnerability was discovered in TeamViewer DEX Platform On-Premises (former 1E DEX Platform On-Premises) prior to version 9.2. Improper input validation allows authenticated users with at least questioner privileges to inject commands in specific instructions. Exploitation could lead to execution of elevated commands on devices connected to the platform.

 

The vulnerability has been fixed with version 9.2 (On-Premises). We recommend updating to the latest available version. No action is required for TeamViewer DEX SaaS customers and users.

 

At this time, there is no indication that this vulnerability has been exploited in the wild.
