Name of the Vulnerable Software and Affected Versions Oracle MySQL Server versions 8.0.23 and prior

Description The issue is related to insufficient input validation in the Server: Group Replication Plugin component of Oracle MySQL Server. It allows a high-privileged attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server. Successful attacks can result in unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Server.

Recommendations For Oracle MySQL Server versions 8.0.23 and prior, update to a version later than 8.0.23 to resolve the issue. As a temporary workaround, consider restricting access to the Server: Group Replication Plugin component to minimize the risk of exploitation.
