This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, such as wp-config.php, which can contain sensitive information. Successful exploitation requires a form whose email notification has the \u201cAttach Files\u201d setting enabled and that contains a field with a meta key matching /signature_/ (for example, a text field labelled \u201cSignature\u201d), with the notification routed to an attacker-supplied email address so the exfiltrated file is delivered to the attacker.
