Adobe Experience Manager versions 6.5.20 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. This vulnerability could allow an attacker to execute arbitrary JavaScript code in the context of the victim's browser session. Exploitation of this issue requires user interaction, typically in the form of convincing a victim to visit a maliciously crafted web page or to interact with a maliciously modified DOM element within the application.
