Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.50%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Insufficient authentication security controls in the browser-based authentication components in Amazon Athena ODBC driver before 2.1.0.0 might allow a threat actor to intercept or hijack authentication sessions due to insufficient protections in the browser-based authentication flows. To remediate this issue, users should upgrade to version 2.1.0.0.
