Technical details

A stored Cross-Site Scripting (XSS) vulnerability exists in Adobe Experience Manager Forms JEE due to improper neutralization of input during web page generation (CWE-79). An unauthenticated remote attacker can inject malicious JavaScript into vulnerable form fields. This script is stored on the server and executes in the context of any user who subsequently views the affected page. Because the vulnerability has a 'Changed' scope (S:C) and high impact on confidentiality and integrity, it can be used to bypass same-origin policies and gain elevated access to victim sessions. Users are advised to update to the latest patched versions as specified in Adobe advisory APSB26-57.
