amazon-redshift-python-driver is the official Python connector for Amazon Redshift. In versions 2.1.13 and earlier, the driver insufficiently validates data received from the server during query result processing. A rogue server or man-in-the-middle could leverage this to execute arbitrary code on the client.
Amazon Redshift Python Connector is a pure Python connector to Redshift (i.e., driver) that implements the Python Database API Specification 2.0. When the Amazon Redshift Python Connector is configured with the BrowserAzureOAuth2CredentialsProvider plugin, the driver skips the SSL certificate validation step for the Identity Provider.
A SQL injection in the Amazon Redshift Python Connector in version 2.1.4 allows a user to gain escalated privileges via schema injection in the get_schemas, get_tables, or get_columns Metadata APIs. Users should upgrade to the driver version 2.1.5 or revert to driver version 2.1.3.
