Technical description

The WP YouTube Lyte WordPress plugin before 1.7.16 did not sanitise or escape its lyte_yt_api_key and lyte_notification settings before outputting them back in the page, allowing high privilege users to set XSS payload on them and leading to stored Cross-Site Scripting issues.
