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 praisonaiagents 1.6.58 版本之前， 会调用 ，该方法仅检查主机名的字面编码，而在执行 、 、 、 或 URL 提及（URL-mention）抓取等需要建立连接的操作之前，并不会解析 DNS 名称。因此，攻击者可以控制一个主机名，使其解析到回环地址、私有地址、链路本地地址或云元数据服务地址，从而绕过 SSRF（服务端请求伪造）防护策略，且无需依赖 DNS 重绑定竞态条件，导致内部响应可能暴露给智能体。该问题已在 praisonaiagents 1.

Vulnerability Title
praisonaiagents: SSRF guard validates literal IPs only and never resolves DNS
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, SpiderTools._validate_url calls _host_is_blocked, which checks literal host encodings but does not resolve DNS names before scrape_page, crawl, extract_links, extract_text, or URL-mention fetches connect. An attacker-controlled hostname resolving to a loopback, private, link-local, or cloud-metadata address therefore bypasses the SSRF policy without a rebinding race and can expose internal responses to the agent. This issue is fixed in praisonaiagents 1.6.58.
