Executive brief
MySQL Connector/Python is a database driver library used to connect Python applications to MySQL databases. A low-privileged attacker with local access to the system running this connector can modify sensitive data in the connector's accessible storage without authorization. The vulnerability affects version 2.1.5 and earlier, though the practical impact is limited since exploitation requires existing local system access.
Technical details
This vulnerability in MySQL Connector/Python (versions 2.1.5 and earlier) allows a local attacker with low-level system privileges to perform unauthorized data modification. The vulnerability requires local system access and low-level privileges but no special interaction or elevated permissions; it results in integrity impact through unauthorized update, insert, or delete operations on data accessible to the connector component. The CVSS 3.0 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) indicates local attack vector, low complexity, and impact limited to integrity. The root cause appears related to insufficient access controls on connector data or resources.
