# CVE-2026-8838

> 9.3 CRITICAL · 🧪 PoC

## Beschreibung

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.
