CVE-2026-41423— Angular 代码问题漏洞

Angular: SSRF via protocol-relative and backslash URLs in Angular Platform-Server

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.21, 20.3.19, 21.2.9, and 22.0.0-next.8, a Server-Side Request Forgery (SSRF) vulnerability exists in @angular/platform-server due to improper handling of URLs during Server-Side Rendering (SSR). When an attacker sends a request such as GET /\evil.com/ HTTP/1.1 the server engine (Express, etc.) passes the URL string to Angular’s rendering functions. Because the URL parser normalizes the backslash to a forward slash for HTTP/HTTPS schemes, the internal state of the application is hijacked to believe the current origin is evil.com. This misinterpretation tricks the application into treating the attacker’s domain as the local origin. Consequently, any relative HttpClient requests or PlatformLocation.hostname references are redirected to the attacker controlled server, potentially exposing internal APIs or metadata services. This issue has been patched in versions 19.2.21, 20.3.19, 21.2.9, and 22.0.0-next.8.

服务端请求伪造(SSRF)

Angular 代码问题漏洞

Angular是Angular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 19.2.21之前版本、20.3.19之前版本、21.2.9之前版本和22.0.0-next.8之前版本存在代码问题漏洞，该漏洞源于@angular/platform-server中URL处理不当，可能导致服务器端请求伪造，使攻击者控制本地源并重定向请求。
