Name of the Vulnerable Software and Affected Versions Amazon Redshift Python Connector versions prior to 2.1.7

Description The issue arises when the Amazon Redshift Python Connector is configured with the BrowserAzureOAuth2CredentialsProvider plugin, causing the driver to skip the SSL certificate validation step for the Identity Provider. This could allow an actor to intercept the token exchange process and retrieve an access token.

Recommendations For Amazon Redshift Python Connector versions prior to 2.1.7, upgrade to version 2.1.7 to address this issue and ensure any forked or derivative code is patched to incorporate the new fixes. As a temporary workaround, consider disabling the BrowserAzureOAuth2CredentialsProvider plugin until the upgrade is complete.
