CVE-2026-57725Network attack vector

Unauthenticated stored cross-site scripting

Published Jul 13, 2026 · Updated Jul 13, 2026

Stored cross-site scripting in Themeum Kirki 6.0.11 and earlier allows remote attackers to inject scripts that execute in visitors' browsers. Patchstack has not published the affected request, parameter, function, or missing output-encoding operation, so the concrete storage and rendering locus remains undisclosed. Exploitation is unauthenticated but requires a privileged user to perform an action, and successful payloads can alter page content or access browser-visible data in that user's session.
