Miggo AIRoot Cause Analysis

The vulnerability stems from two key patterns:

  1. In FileModelProxy.java, the severityColumn method directly appended user-controlled values (violation.getSource() and getSourceDetail()) to HTML output without escaping, as shown in the pre-patch code. The fix added Functions.escape() wrappers.
  2. Multiple Jelly templates lacked the <?jelly escape-by-default='true'?> directive and used unsafe ${} expressions. The patch added escaping directives and replaced some ${} with <j:out> tags with implicit escaping. Both patterns allowed injection of raw HTML/scripts through violation data that wasn't properly sanitized before rendering.
