What is CVE-2025-3047?

A security vulnerability exists in the AWS Serverless Application Model Command Line Interface (SAM CLI) when utilizing Docker for the build process that involves symbolic links. This flaw allows unauthorized users to exploit elevated permissions granted by the tool, granting them access to sensitive host files. By leveraging symlinks, an attacker can copy these restricted files to less secure locations within the container environment. Users are advised to upgrade to version 1.133.0 or later and ensure any derivative code is also patched to mitigate this security risk.
