Affected versions of this package are vulnerable to Command Injection in the SubprocessSandbox module due to the use of shell=True in subprocess.run() combined with an incomplete blocklist that does not prevent execution of sh or bash. An attacker can execute arbitrary system commands by bypassing the blocklist using shell invocation techniques.
Note: This is only exploitable if the sandbox is configured in STRICT mode and untrusted input is passed to the sandbox execution process.
