An authenticated attacker can gain full control of the server hosting PraisonAI.
Recommendation
Upgrade PraisonAI to version 1.5.90 or later.
Original NVD description (English source)
PraisonAI is a multi-agent teams system. Prior to version 1.5.90, execute_code() in praisonai-agents runs attacker-controlled Python inside a three-layer sandbox that can be fully bypassed by passing a str subclass with an overridden startswith() method to the _safe_getattr wrapper, achieving arbitrary OS command execution on the host. This issue has been patched in version 1.5.90.
