The vulnerability involves stored XSS in form fields requiring low privileges. Common attack vectors in Magento include customer registration forms, CMS content editing, and product management interfaces. While no specific patch details are available, these components are: 1) Core user input handlers (Account\Save), 2) CMS content persistence points (Page\Save), and 3) Frontend rendering mechanisms (Product\View). The confidence is medium as these are typical XSS vectors in Magento, but without commit diffs, we can't confirm exact vulnerable functions.
