CVE-2025-3047

Path Traversal in AWS SAM CLI allows file copy to build container

State: Published
Severity: 6.9 Medium
Published: Mar 31, 2025
Updated: Oct 14, 2025
Reserved: Mar 31, 2025

Description

When running the AWS Serverless Application Model Command Line Interface (SAM CLI) build process with Docker and symlinks are included in the build files, the container environment allows a user to access privileged files on the host by leveraging the elevated permissions granted to the tool. A user could leverage the elevated permissions to access restricted files via symlinks and copy them to a more permissive location on the container.

Users should upgrade to v1.133.0 or newer and ensure any forked or derivative code is patched to incorporate the new fixes.
