2DescriptionCVE.org
Vulnerability in the MySQL Cluster product of Oracle MySQL (component: Cluster: General). Supported versions that are affected are 8.0.0-8.0.48, 8.4.0-8.4.11 and 9.7.0-9.7.2. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP 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 7.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H).
AnalysisAI
Full takeover of Oracle MySQL Cluster is achievable by an unauthenticated remote attacker over HTTP across three active release trains: 8.0.0-8.0.48, 8.4.0-8.4.11, and 9.7.0-9.7.2. The attack carries high complexity and requires human interaction from a victim user, but successful exploitation yields complete confidentiality, integrity, and availability compromise of the cluster. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The CVSS vector (AV:N/AC:H/PR:N/UI:R) confirms the attack requires no authentication but mandates human interaction from a person other than the attacker - the victim must perform a specific action (e.g., clicking a link, submitting a form, or triggering a request) to complete exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H yields a score of 7.5, reflecting genuinely high impact constrained by two meaningful friction factors: AC:H (a specific precondition or timing dependency must align) and UI:R (a cluster user or administrator must take an action the attacker induces). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply Oracle's August 2026 Critical Patch Update, available at https://www.oracle.com/security-alerts/cspuaug2026.html, which addresses this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Oracle MySQL Cluster deployments to identify affected versions; enable enhanced logging for HTTP traffic to these systems and review recent access logs for suspicious patterns; restrict network access to MySQL Cluster ports to trusted administrative hosts only. …
