Authenticated reflected XSS via unescaped admin input
Published Jan 17, 2022 · Updated Aug 3, 2024
Reflected XSS in PluginOps Landing Page Builder before 1.4.9.6 allows remote authenticated users to execute script via an admin page. The page-builder-add handler for the ulpb_post admin page reflects an attacker-controlled request value into its response without output escaping. Exploitation requires access to that administrative surface and a victim to open the crafted request, enabling script execution in the victim's browser context.
