CVE-2026-97662 - Argument injection in AWS security-agent-mcp-server diff scan

Bulletin ID: 2026-121-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 10/01/2026 10:30 AM PDT Description: security-agent-mcp-server is an open-source Model Context Protocol (MCP) server, published by AWS in the awslabs/mcp repository, that AI assistants use to run local security scans (including differential "diff" scans) over source code. We identified CVE-2026-97662, an argument injection issue in the diff scan operation: a crafted reference value supplied to the scan is interpreted as a command-line option rather than a revision, which lets a context-dependent actor create, overwrite, or truncate arbitrary files on the host outside the intended workspace directory, bypassing the server's workspace-confinement control. Impacted versions: >= 0.1.1 AND < 0.2.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
