Prior to 20.3.30, 21.2.22, and 22.1.4, Angular server-side rendering (SSR) in @angular\/platform-server serializes ProcessingInstruction DOM nodes inside fallback raw-content elements without escaping matching ancestor closing tags. ProcessingInstruction data escaped greater-than characters but left less-than characters untouched and did not inspect fallback ancestors, so data such as a matching closing tag prematurely terminates noscript, iframe, noembed, or noframes containers. The vulnerable nodes cannot be authored through standard Angular templates; reachability requires application or library code using inject(DOCUMENT).createProcessingInstruction with attacker-controlled data or Renderer2 DOM insertion inside a fallback container. In HTML5 RAWTEXT parsing, the premature close causes subsequent sibling elements to be interpreted as live HTML and enables arbitrary JavaScript execution in a victim&#8217;s browser. This issue is fixed in versions 20.3.30, 21.2.22, and 22.1.4.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Angular is a development platform for building mobile and desktop web applications using TypeScript\/JavaScript and other languages.
