SQL injection attack -- what to do?

I just submitted this to tech support as well, but I thought I’d run it past the folks here as well. If this is duplicative in some way, please feel free to delete.

I’ve been receiving a number of spammy submissions that appear to be an attempt at SQL injection. At least that’s what it looks like – SQL commands submitted via my form.

Am I at risk for an imment hack? What should I be doing?

These seem to be sporadic and come in waves – I’ll get 50-60 submissions with various SQL commands. Then it goes away for a few weeks.

Hello John. I see that you received a reply from support already. I will close this topic and we’ll use the support ticket instead. Thank you.
