Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Packagist wwbn/avideo versions 26.0 and earlier are affected. The endpoint objects/emailAllUsers.json.php lets an administrator send HTML email to every registered user but does not validate a CSRF token. An attacker who lures a logged-in administrator to a malicious page can send arbitrary HTML phishing email to all users through the platform's SMTP server. No fixed version is listed; the source suggests adding CSRF token validation to the endpoint after the admin check.
