Code Review

This pull request, automatically generated by Snyk, aims to upgrade the Python base image in the Dockerfile to fix security vulnerabilities. However, the proposed upgrade to python:3.14.0rc1-slim-bullseye introduces a critical issue. The new version is a release candidate, which is not stable for production use. More importantly, it is incompatible with the project's Python version constraint (<3.12) defined in pyproject.toml, which will cause the application build to fail. My review provides a comment to address this by suggesting a stable and compatible Python image tag that should also resolve the security concerns.

critical

This change introduces two critical issues:

  1. Use of a Release Candidate: The image python:3.14.0rc1-slim-bullseye uses a release candidate (rc1) of Python. Release candidates are not stable, are intended for testing purposes only, and should not be used in production environments.

  2. Python Version Incompatibility: Your pyproject.toml file specifies a Python version constraint of ^3.10,<3.12. The poetry install command in this Dockerfile will fail because Python 3.14.0rc1 does not satisfy this constraint.

To fix the security vulnerabilities while maintaining stability and ensuring the build passes, I recommend using a stable, compatible version. Using a floating tag for the latest patch release of Python 3.11 is a good practice for receiving security updates.

I suggest using python:3.11-slim-bullseye, which will pull the latest stable 3.11.x version on the bullseye base, likely including the necessary OS-level security fixes.
