Pull request overview

This PR attempts to upgrade the Python Docker base image from 3.13.7-slim to 3.14.1-slim to address 3 OpenSSL-related security vulnerabilities (CVE-2025-9230, CVE-2025-9231, CVE-2025-9232) in the Debian 13 base image.

Key Changes:

  • Updates Python base image version in both builder and runtime stages of the Dockerfile
  • Targets OpenSSL vulnerability mitigation through base image upgrade

Critical Issue: Python 3.14.1 does not exist as a released version as of January 2025, making this upgrade invalid and non-functional.

💡 Codex Review

COPY --from=builder /usr/local/lib/python3.13/site-packages /usr/local/lib/python3.13/site-packages

P1 Badge Align site-packages copy with Python 3.14 base

Builder and runtime bases were bumped to python:3.14.1-slim, but the multi-stage copy still pulls /usr/local/lib/python3.13/site-packages. In a 3.14 image that path does not exist, so docker build will fail at this COPY step (no source directory) whenever the judge image is built after this upgrade. Update the copy to the 3.14 site-packages path to restore a working build.

Code Review

This pull request, automatically generated by Snyk, upgrades the Python base image in services/arms/judge/Dockerfile from 3.13.7-slim to 3.14.1-slim to fix security vulnerabilities. While the upgrade is necessary, the current implementation will break the Docker build due to a hardcoded path for site-packages that references the old Python version. I've left a critical comment on how to fix this. Additionally, I've noticed that several other Python-based services in this repository (coder, planner, retriever, safety-guardian, orchestrator) use a similar Dockerfile structure with hardcoded Python version paths. These will also need to be updated to prevent similar issues in the future and to maintain consistency. It would be beneficial to address these in a systematic way, perhaps by using an ARG for the Python version in all Dockerfiles.

# syntax=docker/dockerfile:1
# Judge Arm Dockerfile - Multi-stage build for Python service
FROM python:3.13.7-slim as builder
FROM python:3.14.1-slim as builder

This version upgrade will break the Docker build. The COPY instruction on line 41 uses a hardcoded path with the old Python version (3.13) for both the source (from this builder stage) and the destination (in the runtime stage defined on line 26).

# services/arms/judge/Dockerfile:41
COPY --from=builder /usr/local/lib/python3.13/site-packages /usr/local/lib/python3.13/site-packages

With the base images updated to python:3.14.1-slim, the site-packages directory will be at /usr/local/lib/python3.14/site-packages. The COPY instruction will fail because the source path /usr/local/lib/python3.13/site-packages will not exist in the builder stage.

To fix this, the version number in the path on line 41 must be updated to 3.14 for both source and destination.

A better long-term solution would be to use an ARG for the Python version to avoid this kind of issue in the future. For example:

ARG PYTHON_VERSION_SHORT=3.14
ARG PYTHON_VERSION_FULL=3.14.1
FROM python:${PYTHON_VERSION_FULL}-slim as builder
...
COPY --from=builder /usr/local/lib/python${PYTHON_VERSION_SHORT}/site-packages /usr/local/lib/python${PYTHON_VERSION_SHORT}/site-packages

This way, you only need to update the ARGs at the top of the file.
