Drag and Drop File Upload for Elementor Forms <= 1.6.0 - Unauthenticated Arbitrary File Upload via 'type' Parameter

Published Sep 10, 2026 · Updated Sep 10, 2026 · Assigned by Wordfence

Vendor: add-ons.org Product: Drag and Drop File Upload for Elementor Forms Category: Web / CMS

Description

The Drag and Drop File Upload for Elementor Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.6.0 via the elementor_file_upload function. This is due to insufficient file type validation in the is_file_type_valid() function, which uses the attacker-controlled 'type' parameter as regex keys in the MIME allowlist, allowing blacklist bypass via a crafted extension that sanitize_file_name() later normalizes to a PHP extension. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
