英文原文描述

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, 21.2.16, 20.3.24, and 19.2.25, a Cross-Site Scripting (XSS) vulnerability exists in @angular/platform-server's DOM emulation dependency (domino) when serializing the content of elements. When rendering dynamic text content inside a element via template bindings (such as {{ value }} or [textContent]), the template engine expects the browser to render the content safely. Under Server-Side Rendering (SSR), domino is configured with scripting enabled, meaning is treated as a raw-text element. However, domino's serializer completely omitted from the list of raw-text elements requiring closing-tag escaping during DOM serialization. As a result, any occurrence of in the bound dynamic text was never escaped under any circumstances. The unescaped closing tag was serialized directly into the output HTML (e.g. ). When parsed by a browser, it closes the block early, allowing the injected
