CVE-2026-69149
CVE-2026-69149 — Angular SSR: Missing Fallback Raw-Content Serialization Escaping leads 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 20.3.27, 21.2.19, and 22.0.7, a Cross-Site Scripting (XSS) vulnerability exists in @angular/platform-server's DOM emulation dependency (domino) when serializing the content of fallback raw-content elements (<iframe>, <noembed>, <noframes>, and <noscript>). This issue is fixed in versions 20.3.27, 21.2.19, and 22.0.7.
