Code Review

This pull request from Snyk upgrades the Debian base image to 13.3-slim to resolve several security vulnerabilities. This is a positive and necessary change. My review includes one suggestion to further enhance the security and reproducibility of the Docker build by pinning the base image to its content digest.

[gemini-code-assist]

For improved security and build reproducibility, it is a best practice to pin Docker base images to their immutable digest rather than a mutable tag. While 13.3-slim is specific, the tag can be overwritten. Pinning to a digest guarantees that builds are always based on the exact same image, preventing unexpected changes or security issues from a retagged image.

To apply this, you can find the image digest on Docker Hub or by inspecting the image locally, and then update the FROM instruction like so:

FROM debian:13.3-slim@sha256:<your_image_digest_here>
