user@debugger:~/project$ node app.js
Banned users who are verified and have 2FA are incorrectly granted access. The `not is_banned` check is bypassed due to operator precedence (`and` before `or`), so the expression evaluates as `(not banned and is_owner) or (verified and has_2fa)` instead of `not banned and (is_owner or (verified and has_2fa))`.
