The escapeJs/escapeJson methods in 4 HTML exporter classes were missing critical escapes: - Forward slash (/) — allows </script> tag injection (CWE-79) - Backtick and dollar sign — template literal injection - Unicode line separators (U+2028/U+2029) — break JS string literals - Single quotes — break attribute contexts Created a shared HtmlExportUtils.escapeJs() utility with comprehensive escaping and updated all 4 affected exporters to delegate to it: - GraphDiffHtmlExporter - CentralityRadarExporter - GraphAlgorithmAnimator - GraphTimelineExporter
