Impact

A flaw in Oracle's MySQL Connector/J allows an unauthenticated attacker who can reach the connector over HTTP to compromise the service, potentially gaining full control. The vulnerability results in full confidentiality, integrity, and availability loss for the affected connector. The CVSS 3.1 Base Score of 8.1 reflects that no user interaction or privilege escalation is required for exploitation.

Affected Systems

Oracle Corporation’s MySQL Connectors, specifically Connector/J version 26.7.0. No other versions or products are currently known to be affected.

Risk and Exploitability

With an AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H vector, the risk is significant. The EPSS score is not available, and the vulnerability is not yet listed in the CISA KEV catalog, suggesting that large‑scale exploitation is not proven. Nevertheless, the high CVSS score and lack of authentication requirements make it a high‑priority target for attackers. Organizations should treat any exposure of this connector to public or untrusted networks as a critical threat.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Block external HTTP traffic to the MySQL Connector/J service with a firewall rule to prevent unauthenticated access.
  • Upgrade the MySQL Connector/J library to a newer version that is not listed as affected by Oracle, if such a version exists.
  • If an immediate upgrade is not feasible, apply application‑level filters or input sanitization rules that reject suspicious requests to the connector.
  • Monitor system and network logs for anomalous requests or activity that may indicate attempted exploitation.
