CVE-2026-69149Network attack vector

Same-origin XSS via unescaped fallback raw text

Published Aug 3, 2026 · Updated Aug 3, 2026

Cross-site scripting in Angular SSR before 20.3.27, 21.2.19, and 22.0.7 allows remote attackers to execute script in a visitor's browser. Domino emits bound text nodes inside iframe, noembed, noframes, and noscript as raw HTML, so an injected closing tag escapes the element. Exploitation requires an SSR-rendered page to bind attacker-controlled data in one of those elements and a user to visit it, enabling same-origin session theft or unauthorized actions.
