## Technical details

A DOM-based Cross-Site Scripting (XSS) vulnerability exists in Adobe Experience Manager (AEM) versions 6.5.24, FP11.7 and earlier. The flaw resides in the improper neutralization of input during web page generation (CWE-79), allowing an attacker to manipulate the DOM environment. To exploit this, a remote attacker with low privileges must convince a victim to visit a specially crafted URL. Successful exploitation enables the execution of arbitrary JavaScript in the context of the victim's browser session, potentially leading to session hijacking or unauthorized data access. Adobe has addressed this in security bulletin APSB26-34.
