CVE-2026-66607Network attack vector

Script execution via reflected XSS

Published Aug 20, 2026 · Updated Aug 20, 2026

Cross-site scripting in ThemeHunk Advance Product Search 1.4.8 and earlier allows remote attackers to execute script in a victim browser. The CNA record and ThemeHunk's WordPress.org changelog identify an XSS issue fixed in 1.4.9, but neither source publishes the affected parameter, request path, or output sink, so the exact locus remains undisclosed. Exploitation requires user interaction because the payload must be rendered in a browser, and the published record describes browser-context impact under the site's origin rather than direct server-side code execution.
