Login page password-guessing attack

How it was found

A brute-force attack is an attempt to discover a password by systematically trying every possible combination of letters, numbers, and symbols until you discover the one correct combination that works.

hackerone.com page doesn't have any protection against password-guessing attacks (brute force attacks). It's recommended to implement some type of account lockout after a defined number of incorrect password attempts.

I personally tried many times with wrong password even though no account lockout was detected.

Fix : Implement captcha
