CWE-94Published: May 18, 2026· Updated: May 19, 2026
Official Description
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.
Risk Analysis
This critical vulnerability in the amazon-redshift-python-driver allows for arbitrary code execution on the client due to unsafe use of Python's eval() function on server-received data. With a CVSS score of 9.8, this flaw poses a severe risk, enabling a rogue server or man-in-the-middle attacker to compromise the client system. The absence of an EPSS score means the exploitation likelihood is not yet assessed, but the high CVSS score demands immediate attention.
No public exploit is currently known for this vulnerability. This flaw is remotely exploitable without user interaction, potentially through a malicious server or a man-in-the-middle attack.
Users should upgrade the amazon-redshift-python-driver to version 2.1.14 to remediate this arbitrary code execution vulnerability.
Technical Analysis
CVE-2026-8838 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
