CVE-2026-8838: CWE-94: Improper Control of Generation of Code ('Code Injection') in AWS Amazon Redshift connector for Python
CVE-2026-8838 is a critical vulnerability in the AWS Amazon Redshift connector for Python prior to version 2. 1. 14. It involves unsafe use of Python's eval() function on data received from the server within the vector_in() function, which can allow a rogue server or man-in-the-middle attacker to execute arbitrary code on the client. The vulnerability has a CVSS score of 9. 8, indicating high severity with network attack vector, no privileges required, and full confidentiality, integrity, and availability impact. AWS manages remediation for this cloud-hosted service, and users should upgrade to version 2. 1. 14 to address the issue. No known exploits in the wild have been reported at this time.
AI Analysis
Technical Summary
The vulnerability CVE-2026-8838 in the Amazon Redshift connector for Python arises from improper control of code generation (CWE-94) due to unsafe use of Python's eval() on server-supplied data in the vector_in() function. This flaw allows an attacker controlling the server or positioned as a man-in-the-middle to execute arbitrary code on the client system using the affected connector versions before 2.1.14. The vulnerability is critical with a CVSS 3.1 base score of 9.8, reflecting its ease of exploitation over the network without authentication and its severe impact on confidentiality, integrity, and availability. AWS provides a fixed version 2.1.14 to remediate this issue and manages the remediation for this cloud service. Users are advised to upgrade to the patched version promptly.
Potential Impact
Successful exploitation can lead to arbitrary code execution on the client running the vulnerable Amazon Redshift Python connector, potentially compromising the client system's confidentiality, integrity, and availability. The vulnerability can be exploited remotely without authentication, making it highly critical. No known exploits in the wild have been reported so far.
Mitigation Recommendations
AWS manages remediation for this cloud-hosted service. Users should upgrade the Amazon Redshift connector for Python to version 2.1.14 or later to remediate this vulnerability. Check the AWS security bulletin at https://aws.amazon.com/security/security-bulletins/2026-033-aws/ for the latest guidance and confirmation of patch status.
