Fix not verifiedVulnerability in the MySQL Cluster product of Oracle MySQL (component: Cluster: NDB Operator). Supported versions that are affected are 8.0.0-8.0.47, 8.4.0-8.4.10 and 9.7.0-9.7.1. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where MySQL Cluster executes to compromise MySQL Cluster. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Cluster accessible data. CVSS 3.1 Base Score 5.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).

A security-sensitive function is reachable without the authentication check that should protect it.
An attacker operating through local access may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-306: Missing Authentication for Critical Function. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
