CVE-2026-16444

Name of the Vulnerable Software and Affected Versions TeamViewer Desktop Clients versions prior to 15.81.5

Description Improper neutralization of path traversal sequences allows an authenticated remote session participant to write files to unintended locations on the local file system. This occurs through file transfer or virtual file clipboard mechanisms, which can lead to arbitrary file write and potential code execution with the privileges of the affected user. Path traversal is a technique used to access files and directories that are stored outside the web root folder by manipulating variables such as file paths.

Recommendations Update TeamViewer Desktop Clients to version 15.81.5 or later.
