Easily exploitable vulnerability allows   unauthenticated attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server.
  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this   vulnerability can result in unauthorized access to critical data or complete access to all MySQL Server   accessible data as well as unauthorized update, insert or delete access to some of MySQL Server accessible data. (CVE-2021-2307)
