CVE-2026-52725— Angular 跨站脚本漏洞

Angular Template and Dynamic Component Namespace Bypass leading to Cross-Site Scripting (XSS)

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23, an issue in the @angular/core package allows bypassing script-execution restrictions during dynamic component creation. Specifically, the dynamic component instantiation mechanism (createComponent) failed to reject mounting components directly onto a <script> or namespaced script element (such as <svg:script>). This enabled the initialization of custom components on a tag that executes scripts, allowing attackers to hijack or inject script-executing hosts. This flaw enables an attacker who can control the host element or selector parameter passed to createComponent to initialize or mount an Angular component directly onto a <script> tag, leading to execution of untrusted code or client-side Cross-Site Scripting (XSS). This vulnerability is fixed in 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23.

Angular 跨站脚本漏洞

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存在跨站脚本漏洞，该漏洞源于动态组件创建过程中绕过脚本执行限制，可能导致未经身份验证的攻击者控制host元素或selector参数，在script标签上初始化或挂载Angular组件，从而执行未信任代码或客户端跨站脚本攻击。
