CVE-2026-8838

The Amazon Redshift Python driver before version 2.1.14 uses Python's eval() on data received from the server, allowing attackers to run arbitrary code on the client. This flaw can be exploited by a rogue server or a man‑in‑the‑middle attacker. The issue is fixed in driver version 2.1.14 and later.
