What is CVE-2025-6679?
The Bit Form builder plugin for WordPress is susceptible to an arbitrary file upload vulnerability due to inadequate file type validation across all versions up to and including 2.20.4. This flaw allows unauthenticated attackers to upload harmful files on the server hosting the affected site, potentially leading to remote code execution. The exploit is contingent upon the installation and activation of the PRO version, as well as having a published form that includes an advanced file upload element.
