Description
The Spiffy Calendar plugin for WordPress is vulnerable to unauthorized modification of data due insufficient restrictions on the event_author parameter in all versions up to, and including, 4.9.8. This makes it possible for authenticated attackers, with contributor-level access and above, to make an event appear as though it was created by another user.
