Advisory

Source description from Wordfence Intelligence, credited to Ngô Thiên An (ancorn_).

The Colibri Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's colibri_video_player shortcode in all versions up to, and including, 1.0.276 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
