CVE-2025-5279
Issue with Amazon Redshift Python Connector and the BrowserAzureOAuth2CredentialsProvider plugin
Impact
### 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 ### References If you have any questions or comments about this advisory we ask that you contact AWS/Amazon Security via our vulnerability reporting page [1] or directly via email to [aws-security@amazon.com](mailto:aws-security@amazon.com).
