Technical details
The vulnerability is a privilege escalation in Craft CMS versions 5.0.0 through 5.11.1 affecting the public registration flow. When an attacker registers with a deactivated account username, the system reactivates the account under the new password but fails to clear the direct permissions stored in the userpermissions_users table, which were retained from the original account. Exploitation requires public registration to be enabled and is trivial if email verification is disabled.
Affected products
- Craft CMS 5.0.0 before 5.11.2
