Affected versions of this package are vulnerable to Protection Mechanism Failure in the execute_code() function. An attacker can achieve arbitrary command execution on the host system by leveraging access to print.__self__ to retrieve the real builtins module, extracting sensitive functions such as __import__ through dynamic attribute access and runtime string construction, and bypassing AST-based security checks. This allows reading and writing files, exfiltrating environment variables, and executing further malicious actions.
