Question about file uploads

Hi,

It does not necessarily mean the file was uploaded. It could simply be a failed attempt to upload a file via a potential vulnerability.
To understand how PHP and NinjaFirewall handle uploads, see those 3 discussions:

https://wordpress.org/support/topic/log-shows-suspicious-file-uploaded
https://wordpress.org/support/topic/upload-via-admin-ajaxphp

Now if the file was really uploaded, ensure you are using NinjaFirewall’s “File Check” and “File Guard” features. They do a pretty good job when a similar issue occurs.
