## Technical details

A stored Cross-Site Scripting (XSS) vulnerability exists in Adobe Experience Manager due to improper neutralization of input during web page generation (CWE-79). An attacker with low-privileged credentials can submit malicious JavaScript into vulnerable form fields, which is then stored on the server. When a victim subsequently views the affected page, the script executes within the context of the victim's browser session. The vulnerability has a CVSS score of 5.4, reflecting that while it requires user interaction and low privileges, the impact scope is changed. Patches are available in versions 2026.6.0 (Cloud Service), 6.5.25 (On-premise), and SP2 (LTS).
