Descriptions

The EventON WordPress plugin before 2.1.2 does not validate that the event_id parameter in its eventon_ics_download ajax action is a valid Event, allowing unauthenticated visitors to access any Post (including unpublished or protected posts) content via the ics export functionality by providing the numeric id of the post.

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 This makes it possible for unauthenticated attackers to view arbitrary posts (e.g., unpublished or protected) via the ICS export feature.

WordPress EventON Calendar plugin version 4.4 suffers from an insecure direct object reference vulnerability related to posting.
