CVE-2026-8838 PUBLISHED

Remote Code Execution via eval() Injection in amazon-redshift-python-driver

Assigner: AMZN
Reserved: 18.05.2026 Published: 18.05.2026 Updated: 19.05.2026

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.
