CVE-2025-21588

Name of the Vulnerable Software and Affected Versions MySQL Server versions 8.4.0 through 8.4.4 MySQL Server versions 9.0.0 through 9.2.0

Description A vulnerability in the MySQL Server product allows a high-privileged attacker with network access via multiple protocols to compromise the server. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash of the MySQL Server, leading to a denial of service.

Recommendations For versions 8.4.0 through 8.4.4, update to a version outside of this range to mitigate the risk. For versions 9.0.0 through 9.2.0, update to a version outside of this range to mitigate the risk. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
