Affected: PyPI: redshift-connector

### Summary [Amazon Redshift Python Connector](https://docs.aws.amazon.com/redshift/latest/mgmt/python-redshift-driver.html) is a pure Python connector to Redshift (i.e., driver) that implements the [Python Database API Specification 2.0](https://www.python.org/dev/peps/pep-0249/).

When the Amazon Redshift Python Connector is configured with the BrowserAzureOAuth2CredentialsProvider plugin, the driver skips the SSL certificate validation step for the Identity Provider.

### Impact

An insecure connection could allow an actor to intercept the token exchange process and retrieve an access token.

**Impacted versions:** >=2.0.872;<=2.1.6

### Patches

Upgrade Amazon Redshift Python Connector to version 2.1.7 and ensure any forked or derivative code is patched to incorporate the new fixes.

### Workarounds

None
