Bypassing authentication or checks by incorporating a statement that always returns true, and doing an ‘or’ operation with the statement being injected. It manipulates the return value of the SQL statement to make it always return true, so if the website is checking if the statement returned true to indicate, for example, the password is correct, it will now think that was the case.
I did fix it, but had to rewrite a lot of the PHP backend, which took a couple days.
And yes, I did release another website with SQL injection… It was a personal website for my brother and the pagination was vulnerable. I had written a simple CMS for it, but Instead of a password I just generated an obscure URL with completely open access to edit the DB directly.
The pagination got hacked but I fixed it pretty quickly (by checking the page number was in fact a number).
Surprisingly the CMS never got hacked before I moved him over to WordPress.
Younger me learned a lot of web dev lessons the hard way.
ETA: This was all when I was a teen and I had nobody in my life to teach me these things. I was self taught from a PHP book from the library.

So does that imply they already knew the candidate they were hiring, and were just checking if this is the guy?
IDK I didn’t think that much into it lol
I remember the first time I shipped a website with that SQL injection.
It got taken over surprisingly quickly.
Crackers work hard.
Edit: Wait, does that mean you did it again? Haha.
I just wiped the DB and put it back online again.
