Miggo AIRoot Cause Analysis

The commit diff shows the vulnerable code returned raw user input via 'query_string' => $this->queryString in SpecialAsk.php. This value was rendered in the query log without proper HTML escaping, enabling reflected XSS through malicious query parameters. The patch explicitly adds htmlspecialchars() to neutralize dangerous characters, confirming this was the vulnerable code path. The CWE-79 classification and advisory details about Special:Ask endpoint being affected further corroborate this analysis.
