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

PraisonAI 是一个多代理协作系统。在 praisonaiagents 1.6.58 版本之前， 函数仅对初始 URL 进行验证，而随后 函数会使用 跟随重定向。重定向的目标地址不会被重新验证，因此，攻击者可以通过操控爬取目标，将公共 URL 重定向到回环地址（loopback）、内网或云元数据服务，即使 配置为禁用状态。此时，获取到的内部响应会被返回给代理上下文。该问题已在 1.6.58 版本中得到修复。

Vulnerability Title
PraisonAI: SSRF via redirect-following in praisonaiagents web_crawl
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, the web_crawl function validates only the initial URL before _crawl_with_httpx uses httpx.Client(follow_redirects=True). Redirect targets are not revalidated, so an attacker who influences a crawl target can redirect a public URL to loopback, private network, or cloud metadata services while ALLOW_LOCAL_CRAWL remains disabled. The fetched internal response is returned to the agent context. This issue is fixed in version 1.6.58.
