CVE-2026-12530 - Improper neutralization of argument delimiters in AWS Bedrock AgentCore Python SDK install_packages()

Bulletin ID: 2026-044-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 06/17/2026 14:15 PM PDT Description: The AWS Bedrock AgentCore Python SDK (bedrock-agentcore) is an open-source SDK that enables developers to build, deploy, and manage agents on AWS Bedrock AgentCore. We identified CVE-2026-12530, an issue in the install_packages() method of the Code Interpreter client. The method applied an incomplete blocklist to sanitize package name arguments before constructing a 'pip install' shell command executed within the Code Interpreter sandbox. This allowed crafted package name arguments to bypass validation ‐ most critically, pip's '‐‐index‐url' flag, which could redirect package resolution to an third‐party‐controlled PyPI server, and the '-r' flag, which could read and expose arbitrary sandbox files. Impacted versions: AWS Bedrock AgentCore Python SDK (bedrock-agentcore) versions >= 1.1.3 and < 1.6.1 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
