The Events Calendar < 6.15.16.1 - Contributor+ Event/Organizer/Venue Update/Trash via REST API

Description

The plugin is vulnerable to unauthorized modification of data and loss of data due to an improper capability check on the 'can_edit' and 'can_delete' function. This makes it possible for authenticated attackers, with Contributor-level access and above, to update or trash events, organizers and venues via REST API.
