Public or AI PoC available; prioritize validation

Recommended action

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

PraisonAI 是一个多智能体团队系统。在 praisonai 版本 4.6.34 至 4.6.58 之间，虽然 praisonai 服务端的智能体（agents）接口接受 --api-key 参数，但 _create_agents_app() 函数并未对 POST /agents 或 POST /agents/{agent_name} 请求进行身份验证。因此，即使提供了 API 密钥，网络调用者仍可绕过认证，直接调用已配置的智能体。该问题已在版本 4.6.58 中得到修复。

Vulnerability Title

PraisonAI serve agents --api-key is ignored, allowing unauthenticated remote agent execution

Source: CVE Program / CVE List V5

Vulnerability Description

PraisonAI is a multi-agent teams system. From praisonai 4.6.34 until 4.6.58, praisonai serve agents accepts --api-key but _create_agents_app() does not authenticate POST /agents or POST /agents/{agent_name}. A network caller can invoke configured agents without credentials even when an API key was supplied. This issue is fixed in version 4.6.58.
