Vulnerability from github – Published: 2026-01-29 09:31 – Updated: 2026-01-29 09:31

Details

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Nomad-RunPkgStatusRequest instruction. Improper input validation allows authenticated attackers with actioner privilege to run elevated arbitrary commands on connected hosts via malicious commands injected into the instruction’s input field. Users of 1E Client version 24.5 or higher are not affected.

Severity ?

6.8 (Medium)
