Miggo AIRoot Cause Analysis

The vulnerability stemmed from improper HTML neutralization in the f:combobox control. The commit diff shows the critical fix changed 'innerHTML' to 'innerText' in combobox.js line 249, directly addressing HTML interpretation of item labels. The added test case (ComboBoxSEC1525Test) verifies that HTML payloads in combobox items are no longer rendered as DOM elements, confirming this was the vulnerable code path.
