WPBookit WordPress Plugin Unauthenticated Arbitrary File Upload Vulnerability

A vulnerability allowing arbitrary file uploads has been identified in the WPBookit plugin for WordPress, affecting all versions through 1.0.4. The issue arises from inadequate file type validation in the 'image_upload_handle()' function, which is linked to the 'add_booking_type' route. This flaw enables unauthenticated attackers to upload arbitrary files to the server, potentially leading to remote code execution.

Impact

Exploitation of this vulnerability could allow for arbitrary file uploads, with the potential for remote code execution if the uploaded file is executed on the server.

Remediation

Users are advised to update the WPBookit plugin to version 1.0.5 or a newer patched version.
