Miggo AIRoot Cause Analysis

The commit diff shows the vulnerability was fixed by adding Util.xmlEscape() to the getReleaseVersion() method. This method directly returns the user-controlled release version that gets rendered in UI elements. The lack of output encoding in this specific method matches the described XSS vulnerability pattern where attacker-controlled version strings could execute scripts in tooltips. The singular code change in the patch directly correlates to the vulnerability description.
