Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

以下是该漏洞描述的中文翻译： PraisonAI 是一个多智能体团队系统。从 1.2.3 到 1.7.2 版本中， 中的 网络隔离模式存在缺陷：其 函数仅通过注入无效的 和 环境变量来实现所谓的“网络隔离”，并未在操作系统层面建立真正的网络边界。 这意味着，那些忽略这些代理变量的程序可以直接打开套接字（socket），使得本应被隔离的命令能够访问本地主机（localhost）、内部服务、云元数据接口或外部主机，从而可能导致数据泄露。 该问题的初步修复措施已在版本 1.7.2 中发布。

Vulnerability Title
PraisonAI SandboxExecutor network-isolated mode does not block non-proxy-aware network clients
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. From 1.2.3 until 1.7.2, SandboxExecutor network-isolated mode in src/praisonai-ts/src/cli/features/sandbox-executor.ts uses buildEnv() only to inject invalid http_proxy and https_proxy environment variables and does not establish an operating-system network boundary. Programs that ignore those proxy variables can open sockets directly, allowing supposedly isolated commands to reach localhost, internal services, cloud metadata, or external hosts and potentially exfiltrate data. An initial remediation was released in version 1.7.2.
