CVE-2026-17013Public exploitNetwork attack vector

Reflected XSS via unescaped lbstart parameter

Published Aug 12, 2026 · Updated Aug 12, 2026

Reflected XSS in WP Photo Album Plus before 9.2.07.002 allows remote attackers to execute script via a crafted gallery-page link. A gallery page inserts the wppa-lbstart query parameter into the wppaOvlSlideStart inline JavaScript assignment without sanitization or escaping. No authentication is required, but a gallery with at least one photo must be published and a user must open the link; the script then runs in the site's origin.
