Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the MySQL Cluster product of Oracle MySQL (component: Cluster: General). Supported versions that are affected are 7.4.34 and prior, 7.5.24 and prior, 7.6.20 and prior and 8.0.27 and prior. Difficult to exploit vulnerability allows high privileged attacker with access to the physical communication segment attached to the hardware where the MySQL Cluster executes to compromise MySQL Cluster. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of MySQL Cluster. CVSS 3.1 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Vulnerability in MySQL Cluster's general clustering component allows a high-privileged attacker with physical access to the network segment attached to the hardware where MySQL Cluster executes to potentially take over the cluster. Successful exploitation requires human interaction from a person other than the attacker and involves difficult-to-exploit conditions.

MitigationUpgrade MySQL Cluster to a patched version beyond 8.0.27 (or the respective later versions for 7.4.x, 7.5.x, 7.6.x). Additionally, enforce strict physical security and network segmentation on the communication infrastructure supporting the cluster.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm MySQL Cluster installation
    Run 'mysql --version' or check for MySQL Cluster binaries (ndbd, ndb_mgmd) in the system PATH or installed directories. MySQL Cluster is a separate product from standard MySQL Server.
    Affected if MySQL Cluster is installed and the version falls within 7.4.0-7.4.34, 7.5.0-7.5.24, 7.6.0-7.6.20, or 8.0.0-8.0.27
  2. Check NetApp Oncommand Insight
    Query installed packages or check Program Files/Applications for Oncommand Insight presence using system inventory tools.
    Affected if Oncommand Insight is installed (all versions are affected)
  3. Check NetApp Oncommand Workflow Automation
    Query installed packages or check Program Files/Applications for Oncommand Workflow Automation presence using system inventory tools.
    Affected if Oncommand Workflow Automation is installed (all versions are affected)
  4. Verify clustering component is in use
    Confirm that the MySQL Cluster management daemon (ndb_mgmd) and data node processes (ndbd) are actively running or configured, as the vulnerability exists in the general clustering component.
    Affected if MySQL Cluster clustering components are configured or active

The environment is affected if running MySQL Cluster versions 7.4.x through 7.4.34, 7.5.x through 7.5.24, 7.6.x through 7.6.20, or 8.0.x through 8.0.27, OR if NetApp Oncommand Insight or Oncommand Workflow Automation are installed, and the clustering component is actively used.

dbcve · scoped
Upgrade available Upgrade to a release after 8.0.27
Interim mitigation

Upgrade MySQL Cluster to a patched version beyond 8.0.27 (or the respective later versions for 7.4.x, 7.5.x, 7.6.x). Additionally, enforce strict physical security and network segmentation on the communication infrastructure supporting the cluster.

Recommended fix Moderate confidence

MySQL Cluster: upgrade to 8.0.28+, 7.6.21+, 7.5.25+, or 7.4.35+ (prefer 8.0.x latest stable)

  1. 1. Identify the specific MySQL Cluster version currently installed using: `mysql --version` or checking the MySQL service
  2. 2. For MySQL 8.0.x: Upgrade to MySQL 8.0.28 or later (or latest 8.0.x stable release)
  3. 3. For MySQL 7.6.x: Upgrade to MySQL 7.6.21 or later (or migrate to a supported major version like 8.0.x)
  4. 4. For MySQL 7.5.x: Upgrade to MySQL 7.5.25 or later (or migrate to a supported major version like 8.0.x)
  5. 5. For MySQL 7.4.x: Upgrade to MySQL 7.4.35 or later (or migrate to a supported major version like 8.0.x)
  6. 6. For NetApp Oncommand Insight and Oncommand Workflow Automation: Monitor security.netapp.com for vendor patches and apply when available
  7. 7. After upgrade, verify the new version is running: `mysql --version`
  8. 8. Test application functionality to ensure compatibility with the new MySQL Cluster version
Caveat MySQL Cluster upgrades may require cluster rolling restart; review Oracle MySQL 8.0 release notes for any compatibility changes before upgrading from 7.4/7.5/7.6 to 8.0
