Miggo AIRoot Cause Analysis

The vulnerability stems from unescaped user input in rubric fields. The JavaScript code in rubriceditor.js directly injected values into innerHTML without escaping (fixed via Y.Escape.html). In renderer.php, PHP code outputted criterion/level data using htmlspecialchars (insufficient in some contexts) or raw values, later patched to use Moodle's s() function for proper context-aware escaping. These functions handled the vulnerable qualification/rating fields and were explicitly modified in the security patch.
