Vulnerability Overview

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.

Technical Analysis

REMEDIATION: Update to version 1.7.16, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
