CVE-2026-34938 Details
Description
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.
A vulnerability in PraisonAI versions prior to 1.5.90 allows for arbitrary OS command execution by bypassing a three-layer sandbox in the execute_code() function of the praisonai-agents package. This is achieved by passing a string subclass with a modified startswith() method to the _safe_getattr wrapper, enabling execution of attacker-controlled Python code on the host.
Users should update to PraisonAI version 1.5.90 or later.
