CVE-2026-35560: Amazon Athena Odbc

Medium severity, CVSS 5.9. EPSS: 0.4% chance of exploitation in the next 30 days.

Improper certificate validation in the identity provider connection components in Amazon Athena ODBC driver before 2.1.0.0 might allow a man-in-the-middle threat actor to intercept authentication credentials due to insufficient default transport security when connecting to identity providers. This only applies to connections with external identity providers and does not apply to connections with Athena. To remediate this issue, users should upgrade to version 2.1.0.0.

Affected products

• Amazon Athena Odbc: before 2.1.0.0 (fixed in 2.1.0.0)
