Bulletin ID: 2026-007-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 2026/03/16 09:15 AM PDT Description: The AWS API MCP Server is an open source Model Context Protocol (MCP) server that enables AI assistants to interact with AWS services and resources through AWS CLI commands. It provides programmatic access to manage your AWS infrastructure while maintaining proper security controls. This server acts as a bridge between AI assistants and AWS services, allowing you to create, update, and manage AWS resources across all available services. The server includes a configurable file access feature that controls how AWS CLI commands interact with the local file system. By default, file operations are restricted to a designated working directory (workdir), but this can be configured to allow unrestricted file system access (unrestricted) or to block all local file path arguments entirely (no-access). We identified CVE-2026-4270: Improper Protection of Alternate Path exists in the no-access and workdir feature of the AWS API MCP Server versions >= 0.2.14 and = 0.2.14, < 1.3.9 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
