  "details": "Affected versions of cti-transmute improperly handle conversion-table values passed through the search highlighting feature. The highlight() function previously returned the underlying text directly when no search query was supplied, or performed a regex replacement that inserted \u003cmark\u003e tags without first escaping the original content. Because the resulting value is used by an HTML-rendering sink, malicious markup contained in conversion data could be interpreted as HTML rather than displayed as text.\n\nThe fix introduces a shared highlightMatches() helper that first converts special characters such as \u003c, \u003e, \u0026, and quotes into HTML entities. Only after escaping does the code insert the application-controlled \u003cmark\u003e element used for search highlighting.",
