Miggo AIRoot Cause Analysis

The vulnerability requires two key points: 1) Unsanitized ingestion of X-Forwarded-For header into storage, and 2) Unsafe rendering of the stored value. JFinal's typical Controller.getHeader() pattern would handle the first vector, while FreeMarker/JSP templates without proper escaping would handle the second. The admin interface's TOP10 display mentioned in GHSA-8rp2-j3vj-hgj4 confirms the output context. Though exact code isn't available, these components are fundamental to the described attack flow.
