I have installed MailPoet plug in and wordfence alert me a file is reported by Wordfence wysija-newsletters/helpers/render_engine.php
This file is a PHP executable file and contains the word 'eval' (without quotes) and the word 'base64_decode(' (without quotes). The eval() function along with an encoding function like the one mentioned are commonly used by hackers to hide their code. If you know about this file you can choose to ignore it to exclude it from future scans.
Can i ask what i have to do, i can ignore this?
Is a know file.. but i don't understand the code inside.. maybe i have thinked to report wordfence find dangerous file in the plug in MailPoet, i think is a false positve.
