Miggo AIRoot Cause Analysis

The vulnerability stems from unescaped output of user-controlled data in admin panel customer configuration sections. While no explicit patch diffs are available, the CWE-79 classification and Magento's security bulletin indicate improper neutralization during rendering. The functions/templates listed are core components handling customer data display in the admin interface. The high confidence comes from: 1) The vulnerability's stored XSS nature requiring unescaped output 2) Magento's typical use of .phtml templates with $block->escapeHtml() for XSS protection 3) The specific mention of customer configuration privileges in the description, aligning with these customer management components.
