What the vulnerability does
01Description
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_new_customer' route in all versions up to, and including, 1.0.6. The plugin’s image‐upload handler calls move_uploaded_file() on client‐supplied files without restricting allowed extensions or MIME types, nor sanitizing the filename. 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
02Summary
WPBookit versions 1.0.6 and earlier allow unauthenticated attackers to upload arbitrary files to the server 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.
