CVE-2026-19479Network attack vector

Victim-browser script execution via DOM manipulation

Published Sep 8, 2026 · Updated Sep 10, 2026

DOM-based XSS in Adobe Experience Manager 6.5.24 and earlier allows remote authenticated users to execute JavaScript in a victim browser. Adobe identifies DOM-environment manipulation but does not publish the affected client-side component, source, sink, or unsafe DOM operation. Exploitation requires low-privileged access and a victim to visit a crafted webpage, enabling attacker-controlled script execution in that browser context without affecting availability.
