Overview
Affected versions of this package are vulnerable to Command Injection via the constructor when the binary path is sourced from user-influenced configuration, environment variables derived from request data, or concatenated with user-controlled fragments. An attacker can execute arbitrary commands as the PHP process by supplying a crafted binary path value.
Workaround
This vulnerability can be mitigated by verifying that the binary path is executable using is_executable($path) before passing it to the constructor.
