Summary
Craft CMS from 5.0.0 before 5.11.0 contains an authentication bypass (CWE-287) because users/verify-email does not invalidate verification codes for active users. An attacker who obtains a victim's emailed code can submit it to users/set-password after the victim verifies an email change, resetting the password and taking over the account.
