Description

The Bit Form builder plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 2.20.4. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. For this to be exploitable, the PRO version needs to be installed and activated as well. Additionally a form with an advanced file upload element needs to be published.

Affected WordPress components

  • Bit Form – Contact Form, Payment Forms, Multi Step Forms, Calculator & Custom Form Builder Plugin · bit-form
    Confirmed match Active
    Up to and including 2.20.3
    View on WordPress.org
