Update: Nxt code is extremely vulnerable.
We therefore decided to remove source code 5.9 that we decompiled (and got working) from our repository.
Please enlighten us in detail what specific vulnerabilities you are referring to and how they affect users. Remember, be specific and give good detail.
Our apologies, we already removed the source code from the public. Providing more details would only make the problem worse.
Here is the original Github:
