Technical details

A DOM-based Cross-Site Scripting (XSS) vulnerability (CWE-79) exists in Adobe Experience Manager. The flaw occurs when the application improperly neutralizes user-controlled input that is subsequently used to manipulate the Document Object Model (DOM) environment. An authenticated attacker with low privileges can exploit this by enticing a victim to visit a specially crafted URL. Successful exploitation allows the execution of arbitrary JavaScript in the victim's browser session, potentially leading to session hijacking or unauthorized actions. The issue is resolved in Experience Manager as a Cloud Service 2026.6.0 and specific hotfixes for version 6.5.

Affected products
