CVE-2026-15404Network attack vector

Contributor-level stored XSS via unescaped post title

Published Jul 23, 2026 · Updated Jul 23, 2026

Stored XSS in Bulk Page Generator – LPagery 2.5.7 and earlier allows remote authenticated users to run scripts in an administrator's browser. The lpagery_add_filter_text_template_post() admin-footer handler embeds the selected post's raw title in a single-quoted JavaScript string without output encoding. Contributor-level access is required to plant the title, and a higher-privileged user must open an admin URL whose lpagery_template parameter selects that post.
