## Technical details

The attach_entry_files() function in Everest Forms up to 3.6.3 attaches entry field values with meta keys matching /signature_/ to notification emails without path validation, checking only file_exists(). An unauthenticated attacker can exploit this by submitting a form with a signature field containing an arbitrary file path (e.g., /var/www/html/wp-config.php), causing the server to email the file contents to an attacker-controlled address. This requires the Pro add-on's signature field and email-attachment functionality to be active on a form routed to the attacker's email.
