Name of the Vulnerable Software and Affected Versions MySQL Server versions 8.0.22 and prior

Description The issue is related to insufficient access control in the MySQL Server product, specifically in the Server: DML component. 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 hang or frequently repeatable crash (complete DOS) of MySQL Server.

Recommendations For versions 8.0.22 and prior, update to a version later than 8.0.22 to resolve the issue. As a temporary workaround, consider restricting access to the MySQL Server to minimize the risk of exploitation. Additionally, restrict network access via multiple protocols to the MySQL Server until a patch is available.
