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。在版本 4.6.78 之前， 模块通过直接将 参数插值到 f-string 中，生成 Python 服务器代码，然后将该代码写入文件并通过 执行。如果攻击者能够控制 的值（例如通过命令行参数、配置文件或上游 API），就可以注入任意 Python 代码。版本 4.6.78 修复了此漏洞。

Vulnerability Title
PraisonAI: Code Injection via f-string Interpolation in Deploy API Server Generation
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. Prior to version 4.6.78, the `deploy/api.py` module generates Python server code by directly interpolating the `agents_file` parameter into an f-string that is then written to a file and executed via `subprocess.Popen()`. An attacker who controls the `agents_file` value (via CLI argument, configuration, or upstream API) can inject arbitrary Python code. Version 4.6.78 patches the issue.
