CVE-2026-73161 is a stored cross-site scripting vulnerability in CTI-Transmute affecting versions 1.4 and earlier. The issue is in the search highlighting logic used for conversion-table values. The vulnerable highlight() behavior either returned the underlying text unchanged when no search query was provided, or performed a regex-based replacement that inserted application-controlled <mark> tags without first HTML-escaping the original content. Because the resulting string was then passed to an HTML-rendering sink, attacker-supplied markup embedded in conversion data could be rendered as active HTML instead of inert text. The vulnerability is therefore caused by improper neutralization of untrusted input before output in a web page context.
