AI Analysis

Impact

The flaw is located in the Server: Components Services of Oracle MySQL and allows a local attacker who already has logon credentials with high privileges to compromise the MySQL Server or Cluster. This results in full control over the database, giving the attacker the ability to read, modify, and delete any data and to disrupt service availability. Because the CVSS vector indicates local access, high privilege, and no user interaction, exploitation requires only a login to the host and can be performed by any user who can log into the infrastructure running MySQL.

Affected Systems

Affected are Oracle MySQL Server versions 8.4.0 through 8.4.12, 9.7.0 through 9.7.3, and 26.7.0 through 26.7.1. The same ranges apply to Oracle MySQL Cluster, which includes versions 8.0.0 through 8.0.49, 8.4.0 through 8.4.12, 9.7.0 through 9.7.3, and 26.7.0 through 26.7.1.

Risk and Exploitability

The CVSS 3.1 score of 6.7 reflects a moderate to high severity vulnerability that impacts confidentiality, integrity, and availability. With a local attack vector, an attacker who can log onto the host where MySQL executes and possesses high‑privilege credentials can exploit this flaw without additional user interaction. The EPSS score is not available, and the vulnerability is not yet listed in CISA’s KEV catalog, but the risk remains significant for environments where untrusted users can access the database hosts.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade MySQL Server and MySQL Cluster to the most recent releases that exclude the vulnerability (any version beyond 8.4.12 for Server and beyond 8.0.49 for Cluster).
  • Configure the database service to run under a dedicated low‑privilege account and avoid running it as root or any privileged system account.
  • Continuously monitor Oracle’s security advisories and apply any future patches promptly, verifying that the vulnerable versions are removed from production.
