Code Review
This pull request, automatically generated by Snyk, upgrades the Python base image in the agent/Dockerfile from 3.11-slim to 3.13.5-slim. This change aims to address 4 known vulnerabilities, including one critical. The new Python version (3.13.5) is compatible with the project's declared Python version constraint (>=3.10,<3.14) in pyproject.toml.
One suggestion has been made to enhance the Dockerfile's reproducibility and security by pinning the base image to its SHA256 digest. This is a common best practice for Dockerfiles.
As Snyk advises, thorough testing of the application is recommended after merging this upgrade to ensure continued functionality.

For improved reproducibility and to protect against potential tag mutability (where the python:3.13.5-slim tag might be updated to point to a different image layer in the future), consider pinning the base image to its specific SHA256 digest. This aligns with general Docker best practices for ensuring reproducibility and mitigating risks associated with mutable tags, especially for production or agent images.
You can typically find the digest by running:
docker pull python:3.13.5-slimdocker inspect python:3.13.5-slim --format='{{index .RepoDigests 0}}'ordocker images --digests python | grep 3.13.5-slim
Then update the FROM line to use the digest, for example:
FROM python:3.13.5-slim@sha256:actual_digest_value_here AS baseThis ensures you are always using the exact same base image layer that Snyk has recommended and you've tested against.
Snyk has created this PR to fix 4 vulnerabilities in the dockerfile dependencies of this project.
Keeping your Docker base image up-to-date means you’ll benefit from security fixes in the latest version of your chosen image.
Snyk changed the following file(s):
agent/DockerfileWe recommend upgrading to
python:3.13.5-slim, as this image has only 36 known vulnerabilities. To do this, merge this pull request, then verify your application still works as expected.Vulnerabilities that will be fixed with an upgrade:
