CVE-2025-44016 is a vulnerability in TeamViewer DEX Client (formerly 1E client) Content Distribution Service (NomadBranch.exe) for Windows prior to version 25.11. Due to improper input validation, an attacker can send a crafted request that supplies a valid hash while referencing/providing malicious file content, causing the service’s file integrity validation to be bypassed and the malicious file to be treated as trusted and processed. Successful exploitation results in arbitrary code execution in the context of the Nomad Branch service.
