Angular: Sanitization bypass via directive host bindings on concrete host elements in @angular/core and @angular/compiler
Vulnerability Description
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.28, 21.2.20, and 22.1.0, Angular's compiler and runtime in @angular/core and @angular/compiler could omit or select an incorrect sanitizer for security-sensitive directive host bindings because SecurityContext was derived from the declaring directive or component selector rather than the concrete host element. The mismatch is reachable through hostDirectives composition, inherited HostBinding declarations, createComponent with a custom hostElement or dynamic directives, SVG/MathML namespace elements, and tag-neutral selectors such as :not(...). Attacker-controlled href, src, action, xlink:href, or data values can therefore reach DOM attributes without Angular's built-in sanitizer and execute arbitrary JavaScript in the user's browser context. Applications unable to upgrade can use DomSanitizer.sanitize with SecurityContext.URL before assignment or restrict inputs to validated HTTP and HTTPS URL schemes. This issue is fixed in versions 20.3.28, 21.2.20, and 22.1.0.

Angular 跨站脚本漏洞
Vulnerability Description
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 19.2.25及之前版本、20.0.0至20.3.28之前版本、21.0.0至21.2.20之前版本和22.0.0至22.1.0之前版本存在跨站脚本漏洞,该漏洞源于Angular编译器和运行时因SecurityContext从声明指令或组件选择器而非具体宿主元素派生,对安全敏感的指令宿主绑定可能省略或选择错误的清理器,攻击者可通过特制
