Security risk? Our search bar is being tested periodically for vulnerabilities

We saw something similar in October of last year.

16,433 searches for the letter e and a significant number of searches for the number 20. And who is Larry Freeman?

The rest of the unusual SQL-related searches were fewer in quantity.

I thought searches were rate-limited, but perhaps I'm wrong about that.

We have the same thing w/ searches containing "1" & then some code:

These all happened within the last 30 days.

These searches don't cause any mal effects - the code doesn't actually end up running on the site. So I wouldn't call it a security risk - but I also don't know a ton about this topic.

FYI, we've also raised this question to Khoros directly and have received a comforting response:

"We can confidently confirm that the mentioned query, although looks like SQL, is actually a Khoros(Lithium) specific language - LiQL which is well protected against most of common attacks like SQL injections.
