What the vulnerability does
The WPBookit plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the handle_image_upload() function in all versions up to, and including, 1.0.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
Explanation of Vulnerability in Simple Terms
WPBookit versions 1.0.4 and earlier allow authenticated users to upload files without proper validation. An attacker with low-level site access can upload malicious files, potentially gaining control of the site. The vulnerability affects file handling in the plugin and requires a valid user account to exploit.
What an attacker can do
Upload malicious files to the site and run their own code on the server.
Potential impact on your site
An attacker with basic site access can compromise your entire WordPress installation and steal or modify all data.
Conditions required to exploit
Attacker must have a low-privilege user account on the site (e.g., subscriber or contributor role).
