Summary

The EventPrime – Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the save_frontend_event_submission() function in all versions up to, and including, 3.4.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the title and content of arbitrary posts. This can also be exploited by unauthenticated attackers when the allow_submission_by_anonymous_user setting is enabled.
