Technical details
A stored Cross-Site Scripting (XSS) vulnerability exists in Adobe Commerce and Magento Open Source due to improper neutralization of input during web page generation (CWE-79). A low-privileged attacker can inject malicious JavaScript into vulnerable form fields. This script is then executed in the context of a victim's browser when they navigate to the affected page. Because the vulnerability has a 'Changed' scope (S:C), it can be used to transition from the user's browser session to accessing sensitive administrative functions or session tokens. The vulnerability is reachable over the network and requires low-privileged authentication and minimal user interaction (viewing the page). Patching information is available via Adobe advisory APSB26-49.
