CVE-2026-40111— PraisonAI 操作系统命令注入漏洞

PraisonAIAgents has an OS Command Injection via shell=True in Memory Hooks Executor (memory/hooks.py)

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, he memory hooks executor in praisonaiagents passes a user-controlled command string directly to subprocess.run() with shell=True at src/praisonai-agents/praisonaiagents/memory/hooks.py. No sanitization is performed and shell metacharacters are interpreted by /bin/sh before the intended command executes. Two independent attack surfaces exist. The first is via pre_run_command and post_run_command hook event types registered through the hooks configuration. The second and more severe surface is the .praisonai/hooks.json lifecycle configuration, where hooks registered for events such as BEFORE_TOOL and AFTER_TOOL fire automatically during agent operation. An agent that gains file-write access through prompt injection can overwrite .praisonai/hooks.json and have its payload execute silently at every subsequent lifecycle event without further user interaction. This vulnerability is fixed in 1.5.128.

PraisonAI 操作系统命令注入漏洞

PraisonAI是Mervin Praison个人开发者的一个低代码多智能体协作框架。 PraisonAI 1.5.128之前版本存在操作系统命令注入漏洞，该漏洞源于内存钩子执行器将用户控制的命令字符串直接传递给subprocess.run且未进行清理，可能导致shell命令注入。
