Last modified

CVE-2025-3047 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. 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. EPSS estimates a 0.67% chance of exploitation in the next 30 days.
