What the vulnerability does
The WPBookit plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the image_upload_handle() function hooked via the 'add_booking_type' route in all versions up to, and including, 1.0.4. This makes it possible for unauthenticated attackers 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 unauthenticated attackers to upload arbitrary files to the site without restriction. An attacker can upload malicious files—such as PHP scripts—to gain control of the site. No user interaction or authentication is required to exploit this vulnerability.
What an attacker can do
Upload arbitrary files, including executable code, to take over the site.
Potential impact on your site
Complete site compromise: attackers can run code, steal data, modify content, or use the site for malware distribution.
Conditions required to exploit
Network access only; no authentication or user interaction required.
