CVE-2026-12865Network attack vector

Authenticated-session script execution via unescaped request parameters

Published Sep 2, 2026 · Updated Sep 2, 2026

Reflected XSS in 10Web Photo Gallery by 10Web before 1.8.44 allows remote attackers to run JavaScript through crafted admin-page links. The title and paged request parameters are inserted unescaped into input-attribute values, allowing an auto-firing onfocus handler. Exploitation requires a logged-in administrator to open the link; the Shortcode sink also reaches contributors, while the list sink requires more than 20 galleries or albums.
