AWS resolves path traversal flaw in open-source Serverless MCP Server
What happened.Amazon Web Services published security bulletin 2026-164-AWS addressing a path traversal vulnerability in its open-source Serverless Model Context Protocol Server.
Why it matters.Model Context Protocol servers connect agentic AI systems directly to development environments and cloud tooling. When path traversal defects permit prompt-driven file overwrites, autonomous agents become vectors for arbitrary code execution and local credential theft. Platform teams deploying MCP servers must upgrade to version v0.2.1 immediately. Developers should run agent sidecars within isolated containers with read-only root filesystems.
