SQL Injection Attack Detected via libinjection

This was in my error log is this a concern?

Code:

i see the mention of OWASP and so i guess its going to perhaps involve the use of zap ? Their testing app


it also seems to mention sendmail and contact.

Now I have a clone of my web running Apache (localhost) on Arch Linux

I have a view which has a contact form; the text goes to a controller; there is a little bit of checking and if everything is ok it goes to PHPMailer to send an email direct to my email account. So that process doesn't even involve a database.

Using zap on the url that serves up my web 127.0.0.x zap flagged up some issues; i took it as a false positive. Bit in your case is there any interaction with a database to retrive date in which case you migth have to look a bit deeper. In my case sql injection can't be involved on my form->controller-> creates email because the process doesn't even touch a db

CMS CI4     I use Arch Linux by the way
