Unauthenticated profile disclosure via unprotected AJAX handler
Published Jun 26, 2026 · Updated Jun 26, 2026
Missing authorization in bPlugins HTML5 Video Player 2.11.0 and earlier allows remote attackers to read registered-user profile data. The watermark_data AJAX handler exposes a logged-out route and returns email and display-name fields after checking only a page-issued nonce, not a capability. The request requires no account or user interaction, and the demonstrated consequence is limited to disclosure of email addresses and display names.
