Title
File Hash Validation Bypass in NomadBranch.exe
Summary
A vulnerability in TeamViewer DEX Client (former 1E client) - Content Distribution Service (NomadBranch.exe) prior version 25.11 for Windows allows malicious actors to bypass file integrity validation via a crafted request. By providing a valid hash for a malicious file, an attacker can cause the service to incorrectly validate and process the file as trusted, enabling arbitrary code execution under the Nomad Branch service context.
