Description

Summary

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.

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
