Description
The The Events Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure via the iCal export and add-to-calendar links in all versions up to, and including, 6.18.2, due to a missing visibility check on the Venue and Organizer linked to an event. The event templates hide the details of password-protected venues and organizers, but the export prints the venue's full address and the organizer's email address without checking whether the linked post is published or password protected. Linked venue and organizer IDs were also not checked for post type or password protection when an event was saved. This makes it possible for unauthenticated attackers to obtain the address and email details of password-protected or unpublished venues and organizers linked to events they can view.
