BookingPress – Appointment Booking Calendar Plugin and Online Scheduling Plugin < 1.0.88 - Authenticated (Admin+) Arbitrary File Upload

Description The BookingPress plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient filename validation in the ‘bookingpress_process_upload’ function in all versions up to, and including 1.0.87. This allows an authenticated attacker with administrator-level capabilities or higher to upload arbitrary files on the affected site’s server, enabling remote code execution.
