Hi,

I recently had the chance to assess the security of many applications with a back-end written in the Kotlin language. Unfortunately, at the moment Semgrep‘s support for the Kotlin is still in “Beta” and there are not many public rules for this language. So, I decided to write a bunch of them on my own, mainly to look for potential SQL Injections. These rules were written with limited time, they are non-exhaustive, and can definitely be optimized. However, they are field-tested and have proven to do their job quite well.
