Prior to version 1.5.90, run_python() in praisonai constructs a shell command string by interpolating user-controlled code into python3 -c \"<code>\" and passing it to subprocess.run(..., shell=True). The escaping logic only handles \\ and \", leaving $() and backtick substitutions unescaped, allowing arbitrary OS command execution before Python is invoked.
