CVE-2026-8838

9.3 criticalEPSS 0.8%

Critical (9.3). EPSS 0.8% chance of exploitation in the next 30 days. Fixed in redshift-connector 2.1.14.

Unsafe use of Python's eval() on server-received data in the vector_in() function in amazon-redshift-python-driver before 2.1.14 allows a rogue server or man-in-the-middle actor to execute arbitrary code on the client. To remediate this issue, users should upgrade to version 2.1.14.
