The WordPress Email Subscribers & Newsletters Plugin installed on the remote host is affected by an email forgery/spoofing vulnerability in the class-es-newsletters.php class due to missing authentication for a critical function. An unauthenticated, remote attacker can exploit this via a specially crafted ajax request, to send forged email to all recipients from the available lists of contacts or subscribers, with complete control over the content and subject of the email.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
