Frequently Asked Questions
Who is realistically exposed to this vulnerability?
Exposure requires a high-privileged attacker who can log on to the infrastructure hosting MySQL Server or MySQL Cluster. The attacker must also induce human interaction from another person, and exploitation is rated difficult.
What is the likely impact if exploitation succeeds?
A successful attack can cause MySQL Server or MySQL Cluster to hang or crash repeatedly, resulting in a complete denial of service. The provided CVSS vector identifies availability as the only affected security property, with no confidentiality or integrity impact.
Which upstream product versions are identified as affected?
Affected MySQL Server versions are 8.4.0 through 8.4.12, 9.7.0 through 9.7.3, and 26.7.0 through 26.7.1. Affected MySQL Cluster versions are 8.0.0 through 8.0.49, 8.4.0 through 8.4.12, 9.7.0 through 9.7.3, and 26.7.0 through 26.7.1.
