Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Angular是Angular组织开源的一个开发平台。用于使用 Typescript / JavaScript 和其他语言构建移动和桌面 Web 应用程序。 Angular存在服务端请求伪造漏洞，该漏洞源于服务器端渲染引擎处理请求URL时存在服务端请求伪造（SSRF）问题，将绝对形式URL传递给渲染引擎可导致内部ServerPlatformLocation被操纵，使相对HttpClient请求或PlatformLocation.hostname引用重定向到攻击者控制的服务器，可能暴露内部API或元数据服务

Vulnerability Title
Angular: SSRF via Hostname Hijacking in @angular/platform-server
Source: CVE Program / CVE List V5
Vulnerability Description
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.0-next.12, 21.2.13, 20.3.21, and 19.2.22, a Server-Side Request Forgery (SSRF) vulnerability exists in @angular/platform-server. The issue stems from how the server-side rendering (SSR) engine processes the request URL provided to the rendering entry points. When an absolute-form URL (e.g., http://evil.com) is passed to the rendering engine, the internal ServerPlatformLocation can be manipulated into adopting the attacker-controlled domain as the "current" hostname. Consequently, any relative HttpClient requests or PlatformLocation.hostname references are redirected to the attacker controlled server, potentially exposing internal APIs or metadata services. This vulnerability is fixed in 22.0.0-next.12, 21.2.13, 20.3.21, and 19.2.22.
