CVE-2026-47008 Oracle Corporation CVE debrief

Who should care

Administrators and users of MySQL Server and MySQL Cluster versions 9.7.0-9.7.1 should be aware of this vulnerability and take necessary actions to mitigate the risk. They should review official advisories and consider asset inventory and rollback/change windows as part of their remediation strategy to minimize potential impact on service availability and data integrity across high-privileged network-accessible attack surfaces in their organizations' infrastructure and applications that rely on these MySQL products for database management services.

Technical summary

The vulnerability is located in the InnoDB component of MySQL Server and MySQL Cluster. It has a CVSS 3.1 Base Score of 4.9 and a CVSS Vector of (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H). The vulnerability allows a high privileged attacker with network access via multiple protocols to compromise MySQL Server and MySQL Cluster, potentially causing a hang or frequently repeatable crash. Defenders should prioritize patching and compensating controls for exposed systems while verifying monitoring and detection capabilities for suspicious activity related to MySQL Server and MySQL Cluster deployments within their environments.

Defensive priority

Medium-High due to potential for service disruption and high privilege exploitation vector requiring network access via multiple protocols with CVSS 3.1 Base Score of 4.9 and CVSS Vector of (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H). Defenders should prioritize patching and compensating controls for exposed systems while verifying monitoring and detection capabilities for suspicious activity related to MySQL Server and MySQL Cluster deployments within their environments.
