Online Booking & Scheduling Calendar for WordPress by vcita < 4.5.5 - Authenticated (Author+) Arbitrary File Upload

Description

The Online Booking & Scheduling Calendar for WordPress by vcita plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 4.5.3. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
