Summary
Vulnerability in MySQL Server and MySQL Cluster (component: Server: JSON) affects MySQL Server 8.4.0-8.4.12, 9.7.0-9.7.3, 26.7.0-26.7.1 and MySQL Cluster 8.0.0-8.0.49, 8.4.0-8.4.12, 9.7.0-9.7.3 and 26.7.0-26.7.1. A low-privileged authenticated attacker with network access can cause a hang or frequently repeatable crash (complete DoS). CVSS 3.1 Base Score 6.5 (availability impact).
Risk Assessment
Even a low-privilege account can remotely cause database unavailability, potentially disrupting applications that depend on MySQL. The risk is significant in environments with many user accounts that have network access.
Recommendation
Update MySQL Server and MySQL Cluster to a version containing the fix (outside the listed ranges) and restrict network access to the database.
