## Technical details

A vulnerability in the Connector/J component of Oracle MySQL Connectors allows a low-privileged attacker with network access via multiple protocols to compromise the system. The vulnerability is classified as difficult to exploit (Attack Complexity: High). Successful exploitation can lead to unauthorized creation, deletion, or modification of critical data, as well as unauthorized access to all data accessible via the connector. It also allows for a partial denial of service (DoS). The issue affects supported versions 9.7.0 through 9.7.1 and was addressed in the July 2026 Oracle Critical Patch Update.
