Miggo AIRoot Cause Analysis

The vulnerability manifests in HTML page generation with unescaped user input. While exact patch details are unavailable, analysis focuses on: 1) Core data handling classes (DataAccessPointRegistry) that manage dataset names displayed in admin UI 2) Query processing servlets (SPARQL_QueryGeneral) that render user-provided query parameters in HTML responses. These components likely passed dataset names or query parameters to templating systems without adequate output encoding prior to the 4.1.0 patch.
