ARForms is a WordPress form builder plugin used by website administrators to create and manage contact forms and data collection forms. The plugin's file upload functionality allows attackers to upload malicious files without authentication if a form with a file field is published. An attacker can bypass file type restrictions and upload executable PHP code, enabling remote code execution on the affected website.

## Technical details

The ARForms plugin's file upload handler takes the stored filename from an attacker-controlled request header without proper validation. File-type and content-safety checks can be evaded to allow PHP executable files to be written to a publicly accessible directory. Unauthenticated remote attackers can achieve arbitrary file upload and potential remote code execution, provided the target site has a published form containing a File field.
