CVE-2026-35560 Amazon CVE debrief

Who should care

Defenders responsible for Amazon Athena ODBC driver deployments, especially those using external identity providers, should assess exposure and upgrade to version 2.1.0.0. They should also verify connections with external identity providers, monitor for potential man-in-the-middle attacks, and review compensating controls for exposed systems while remediation is scheduled and verified.

Why it matters

CVE-2026-35560 requires verification of Amazon Athena ODBC driver versions and configurations, especially for external identity provider connections, to prevent potential credential interception and man-in-the-middle attacks.

• Potential interception of authentication credentials
• Man-in-the-middle attacks on connections with external identity providers
• Need to verify connections and upgrade to version 2.1.0.0
• Possible impact on data access and authentication

Technical summary

The Amazon Athena ODBC driver before version 2.1.0.0 has an improper certificate validation vulnerability in its identity provider connection components. This allows a man-in-the-middle threat actor to intercept authentication credentials due to insufficient default transport security when connecting to external identity providers. The vulnerability affects Amazon Athena ODBC driver deployments, especially those using external identity providers, and requires verification of driver versions and configurations to prevent potential credential interception and man-in-the-middle attacks.

Defensive priority

Upgrade to version 2.1.0.0 to remediate the issue.

Recommended defensive actions

• Upgrade to version 2.1.0.0
• Verify connections with external identity providers
• Monitor for potential man-in-the-middle attacks
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability and its remediation. The vulnerability is related to improper certificate validation in the Amazon Athena ODBC driver before version 2.1.0.0. The driver does not properly validate certificates when connecting to external identity providers, allowing man-in-the-middle threat actors to intercept authentication credentials.
