What the vulnerability does
The Ebook Store plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ebook_store_save_form function in all versions up to, and including, 5.8012. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
