CVE-2026-47392Public exploitNetwork attack vector

Host command execution via print builtins leak

Published Jul 21, 2026 · Updated Jul 21, 2026

Sandbox escape in PraisonAI before 4.6.40 allows remote authenticated users to execute arbitrary OS commands through crafted agent input. The execute_code() path in praisonaiagents/tools/python_tools.py accepts print.self, exposing builtins; vars() and a runtime-built import key then evade its AST denylist. Any party able to influence agent input through direct code, prompt injection, or a malicious document can act with the PraisonAI process's host permissions.
