Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, an unauthenticated attacker who knows an account email address or username can abuse the account lockout mechanism of a local-authentication collection to prevent that account from signing in. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
