Description
The Hash Form – Drag & Drop Form Builder plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'file_upload_action' function in all versions up to, and including, 1.1.0. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

Fix
Apply the hashthemes hash form security patch or hotfix for CVE-2024-5084 on the affected version, following the vendor advisory for your exact build.
Workarounds
Treat uploaded files as untrusted until proven otherwise: validate the actual content type rather than the supplied extension, store uploads outside the web root on a volume mounted without execute permission, and rename them to server-generated identifiers so an attacker cannot choose the path a request will later resolve. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
