CVE-2025-12695: The overly permissive sandbox configuration in DSPy allows attackers to steal sensitive files in cases when users build

CVE-2025-12695 is a vulnerability in DSPy (a framework for building AI agents) where an overly permissive sandbox configuration (a restricted environment meant to limit what code can do) allows attackers to steal sensitive files when users build an AI agent that takes user input and uses the PythonInterpreter class (a tool that runs Python code). The vulnerability stems from improper isolation, meaning the sandbox doesn't adequately separate the untrusted code from the rest of the system.
