Adobe Experience Manager versions 6.5.19 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable web pages. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable script. This could result in arbitrary code execution in the context of the victim's browser.
