CVE-2026-40158— PraisonAI 安全漏洞

PraisonAI has Improper Control of Generation of Code ('Code Injection') and Protection Mechanism Failure in praisonai

PraisonAI is a multi-agent teams system. Prior to 4.5.128, PraisonAI's AST-based Python sandbox can be bypassed using type.__getattribute__ trampoline, allowing arbitrary code execution when running untrusted agent code. The _execute_code_direct function in praisonaiagents/tools/python_tools.py uses AST filtering to block dangerous Python attributes like __subclasses__, __globals__, and __bases__. However, the filter only checks ast.Attribute nodes, allowing a bypass. The sandbox relies on AST-based filtering of attribute access but fails to account for dynamic attribute resolution via built-in methods such as type.getattribute, resulting in incomplete enforcement of security restrictions. The string '__subclasses__' is an ast.Constant, not an ast.Attribute, so it is never checked against the blocked list. This vulnerability is fixed in 4.5.128.

对生成代码的控制不恰当(代码注入)

PraisonAI 安全漏洞

PraisonAI是Mervin Praison个人开发者的一个低代码多智能体协作框架。 PraisonAI 4.5.128之前版本存在安全漏洞，该漏洞源于基于AST的Python沙箱可通过type.__getattribute__绕过，可能导致任意代码执行。
