Advisory
Source description from Wordfence Intelligence, credited to Miguel Santareno.
The EventON plugin for WordPress is vulnerable to an Insecure Direct Object Reference in versions up to, and including, 7.5.4. This is due to improper validation and authorization checks affecting the eventon_ics_download AJAX action. This makes it possible for unauthenticated attackers to view arbitrary posts (e.g., unpublished or protected) via the ICS export feature.
