No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PraisonAI 是一个多智能体（multi-agent）团队系统。在 1.7.2 版本之前，位于 中的 工具使用 配合 来执行模型生成的 JavaScript 代码。然而，其基于正则表达式的黑名单机制可以被绕过：攻击者可通过 获取全局对象，并通过动态构造 模块名来突破限制。 若攻击者能够影响传入 工具的 参数，则可以利用宿主机进程的能力，读写文件、获取环境变量中的凭证，并以 PraisonAI 进程的权限执行操作系统命令。该问题已在版本 1.7.2 中修复。

Vulnerability Title
PraisonAI: Remote Code Execution via Sandbox Escape in `codeMode` Tool
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. Prior to 1.7.2, the codeMode tool in src/praisonai-ts/src/tools/builtins/code-mode.ts executes model-generated JavaScript with new Function() and with(sandbox), while a regular-expression blocklist can be bypassed with Function('return this')() to recover the global object and by constructing the child_process module name dynamically. An attacker who can influence the code argument can access host process capabilities, read or write files, obtain environment credentials, and execute operating-system commands with the PraisonAI process privileges. This issue is fixed in version 1.7.2.
