Frequently Asked Questions
Which MySQL Server and MySQL Cluster versions are 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.
Does an attacker need MySQL credentials or user interaction to exploit this issue?
No. The issue is described as exploitable by an unauthenticated attacker with network access through multiple protocols, and it does not require user interaction.
What is the practical impact of successful exploitation?
Successful exploitation can cause MySQL Server or MySQL Cluster to hang or crash repeatedly, resulting in a complete denial of service. The provided CVSS vector indicates no confidentiality or integrity impact.
How feasible is exploitation from the network?
The vulnerability is network-reachable, but exploitation is rated difficult and has a high attack-complexity requirement in the CVSS vector. Systems that are reachable by untrusted network clients are the relevant exposure scenario.
