Miggo AIRoot Cause Analysis

The vulnerability stems from improper output encoding when handling the windowId parameter in JSF component rendering. The commit diff shows the fix replaced direct string concatenation ('dswh.init("' + windowId + '"') with proper escaping via writer.writeText(). This matches the CWE-79 XSS pattern of embedding untrusted data without neutralization in web output. The JIRA ticket DELTASPIKE-1307 explicitly references this code location and the XSS risk.
