CVE-2026-16796 is an improper neutralization of argument delimiters vulnerability in the AWS Bedrock AgentCore Python SDK's Code Interpreter package-installation helper. In versions before 1.18.1, the install_packages() method accepts crafted package-name arguments that can bypass validation through pip package extras syntax and reach shell command construction. A remote authenticated user able to influence these arguments can execute arbitrary commands inside the Code Interpreter sandbox.

A command-injection bypass in the Amazon Bedrock AgentCore Python SDK Code Interpreter package-installation helper. It abuses pip package-extras syntax to evade the validation introduced for CVE-2026-12530 and pass shell commands into the Code Interpreter sandbox. Successful exploitation could expose temporary credentials available to a custom Code Interpreter execution role.
A command argument injection vulnerability in the AWS Bedrock AgentCore Python SDK's Code Interpreter package installation flow that allows authenticated users to execute arbitrary commands inside the sandbox container via crafted package extras specifiers.
A command injection vulnerability in the install_packages() method of the AWS Bedrock AgentCore Python SDK before version 1.18.1 that could allow a remote authenticated user to execute arbitrary commands within the Code Interpreter sandbox via crafted package name arguments.
