Descriptions

The Spiffy Calendar WordPress plugin before 4.9.9 doesn't check the event_author parameter, and allows any user to alter it when creating an event, leading to deceiving users/admins that a page was created by a Contributor+.

El complemento Spiffy Calendar de WordPress anterior a 4.9.9 no verifica el parámetro event_author y permite a cualquier usuario modificarlo al crear un evento, lo que lleva a engañar a los usuarios/administradores de que una página fue creada por un Contributor+.

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.
