Vulnerability Title
Open WebUI: SSRF Protection Bypass in Playwright Web Loader via HTTP Redirects
Vulnerability Description
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.6, the SafePlaywrightURLLoader implements a validate_url function to prevent SSRF attacks by checking the IP address of the user-provided URL. However, this validation is performed only on the initial URL. Since Playwright automatically follows HTTP redirects (301/302) by default, an attacker can bypass the validation by providing a safe URL that redirects to a restricted internal network address (e.g., localhost, Docker container network, or Cloud Metadata). This allows the application to access internal services despite ENABLE_RAG_LOCAL_WEB_FETCH being set to False This vulnerability is fixed in 0.9.6.

Vulnerability Title
Open WebUI 服务端请求伪造漏洞
Vulnerability Description
Open WebUI是Open WebUI团队开源的一个可扩展、功能丰富、用户友好的自托管 WebUI。 Open WebUI 0.9.6之前版本存在服务端请求伪造漏洞,该漏洞源于SafePlaywrightURLLoader中的validate_url函数仅对初始URL进行IP检查验证,但由于Playwright默认跟随HTTP重定向,攻击者可通过提供安全URL来绕过验证,导致应用程序访问受限内部网络地址。
