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

Baptiste Arnaud Typebot是Baptiste Arnaud个人开发者的一个可视化聊天机器人构建平台。 Baptiste Arnaud Typebot 3.17.0之前版本存在服务端请求伪造漏洞，该漏洞源于WhatsApp状态转发功能存储的webhook转发URL仅通过通用URL验证，但转发代码使用了原始ky实例而非SSRF保护的safeKy客户端，可能导致攻击者利用服务器向内部服务、私有网络主机、localhost或元数据端点发起HTTP请求。

Vulnerability Title
TypeBot's WhatsApp status forwarding uses unvalidated user-controlled URLs, allowing SSRF from the Typebot server
Source: CVE Program / CVE List V5
Vulnerability Description
TypeBot is a chatbot builder tool. Prior to version 3.17.0, Typebot's WhatsApp status forwarding feature stores a workspace-configured webhook forwarding URL and later POSTs WhatsApp marketing/error status events to it from the server. The stored URL is only validated as a generic URL in settings, but the forwarding code uses the raw `ky` instance instead of the repository's SSRF-protected `safeKy` client. A workspace user who can configure WhatsApp settings can therefore make the Typebot server issue HTTP requests to internal services, private-network hosts, localhost, or metadata-style endpoints whenever the public WhatsApp production webhook receives a status payload that should be forwarded. Version 3.17.0 patches the issue.
