Important warning
Warning
When you have learned to search for vulnerabilities, you will notice that there are actually quite a lot of them, and it is not difficult to find vulnerable targets on the internet. However, it is extremely important that you never launch any kind of attacks or even attempt to see if an application is vulnerable if you do not have legal permission to do so. Committing a data breach can result in fines or imprisonment, but above all, you can ruin your chances of getting a job in the field again.

It makes no sense to throw away the opportunity to work as a hacker all day long, learn from colleagues, and become a top professional in the field just because of foolishness. Not to mention the mental suffering caused by data breaches, both for those whose information has leaked to anyone's hands and for those who were responsible for protecting the data.
Let's stay on the right track!
