Malta has been mentioned? As a person living here I could say that workflow of the government here is bad. Same as in every other place I guess.
By the way, I had a story when I accidentally hacked an online portal in our school. It didn't go much and I was "caught" but anyways. This is how we learn to be more careful.
I believe in every single system like that it's fairly possible to find a vulnerability. Nobody cares about them and people that make those systems don't have enough skill to do it right. Data is going to be leaked. That's the unfortunate truth. It gets worse with the come of AI. Since it has zero understanding of what it is actually it will make mistakes that would cause more data leaks.
Even if you don't consider yourself as an evil person, would you still stay the same knowing real security vulnerability? Who knows. Some might take advantage. Some won't and still be punished for doing everything as the "textbook way".
