Overview
Affected versions of this package are vulnerable to Command Injection via incomplete sanitization of user-supplied commands in the terminal process. An attacker can execute arbitrary operating system commands as the web server user by injecting shell metacharacters such as single pipe (|), backtick (`), or newline (0x0A) into the command input, thereby bypassing the intended command allowlist and argument validation.
