CVE-2026-50556

A flaw was found in @angular/platform-server. This Cross-Site Scripting (XSS) vulnerability exists in its DOM emulation dependency, domino, when handling the content of `<noscript>` elements during server-side rendering. A remote attacker could exploit this by injecting unescaped closing `</noscript>` tags within dynamic text content. This allows for the execution of arbitrary code in the user's browser context, potentially leading to information disclosure or other malicious activities.
