Description
The Instant Appointment plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the -insapp_upload_image_as_attachment- function in all versions up to, and including, 1.2. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site-s server which may make remote code execution possible.
