A command injection vulnerability in TeamViewer Full Client and Host for Linux prior to version 15.81.5 allows a remote attacker to execute arbitrary commands in the context of the current user via a specially crafted URL sent through the out-of-session chat feature. Exploitation requires user interaction by clicking the malicious link.
