## Technical details

A stored Cross-Site Scripting (XSS) vulnerability (CWE-79) exists in Adobe Commerce, Magento Open Source, and related plugins due to improper neutralization of input during web page generation. An attacker with low-level privileges can inject malicious JavaScript into vulnerable form fields. The exploit is triggered when a victim (typically an administrator) navigates to the page where the malicious script has been stored, causing the script to execute within the context of the victim's browser session. This vulnerability has a CVSS score of 5.4, reflecting that while it requires user interaction and authentication, the scope is changed. Patches have been released in the July 2026 security updates.
