Some POST requests give 400 Bad Request when word 'select' is in the body

Hi all,

we have seen that if you add the word 'SELECT' in some requests sometimes
you get a 400 Bad Request. It is a use case where we save contents via POST
to edit a item of our catalog. I suspect that nginx may interpret this
request as a some kind of SQL injection.

Do you know if it is a known bug?

nginx version: nginx/1.15.4
