🏨 The "Hotel Key" Hack (IDOR)

Imagine you check into a hotel and get a room key. You look at your key and see it’s for Room 101.

As you walk down the hallway, you start wondering: "Wait... if I’m 101, what happens if I just walk up to Room 102 and try my key?" In a bad hotel, the lock doesn't care who you are; it only cares that you have a key.

Hackers do this with Web Addresses:

You log into your bank and see your profile at: bank[.]com/user/500

You get curious and change the number in the address bar to: bank[.]com/user/501

Suddenly, you’re looking at Abebe’s bank account balance. 😲

The hacker didn't "break" the door down; they just asked for a different room and the computer was too polite to say, "Hey, you aren't allowed in there!"

🔓Good security doesn't just check if you have a key (Authentication); it checks if that specific door belongs to YOU (Authorization).
