Website hacked through Forminator Vulnerability

Hello,

This isn’t a question, I just have no idea how to contact the developers for this plugin to notify them of a vulnerability that someone used to insert a malicious code file into our websites folder directory called ‘mainhack.php’ within the ‘/plugins/forminator/assets/css’ directory which ultimately ended up crashing our website.

I have a photo of the submission the person used to insert their code file but it seems I can’t upload images from my computer on this post without a URL so if there’s another way to do so let me know.

I’ll add all the fields this person filled out since I’m not sure if any of the fields besides the ‘First Name’ field is actually relevant to exploit this vulnerability.
If it would be possible to get this info to the Forminator developers that would be great.
I’ve since removed Forminator as the Forms plugin for our website and will be seeking a different one with less potential security exploits.
