Arbitrary File Upload Vulnerability in Piotnet Addons for Elementor Pro Plugin

CVE-2026-4885

What is CVE-2026-4885?

The Piotnet Addons for Elementor Pro plugin for WordPress presents a security risk due to its inadequate file type validation in the 'pafe_ajax_form_builder' function. This issue affects all versions up to and including 7.1.70. Specifically, the plugin employs an incomplete blacklist for file extensions, permitting potentially dangerous file types to be uploaded, such as .phar and .phtml. Unauthenticated attackers can exploit this vulnerability to upload arbitrary files to the server, potentially enabling remote code execution if a file field is incorporated in the form. This highlights the critical need for enhanced validation mechanisms within the plugin to safeguard against unauthorized file access.
