Bug Report: [security] — Container Security Enhancement for Supply Chain Protection

Severity Assessment

Impact: Supply chain attacks, dependency vulnerabilities, reproducibility issues
Likelihood: Low to Medium - depends on external threats
Priority: Medium

Location

File: Dockerfile.server
Function/Class: Base image specification
Lines: Line 15

Description

The Dockerfile.server uses tag-based image pinning instead of digest-based pinning, as acknowledged in the comments. While this improves readability, it reduces supply chain security and reproducibility.

Evidence

# NOTE: Base images are pinned by tag (not by digest) for readability and
# ease of updates.  Digest pinning provides stronger reproducibility but
# complicates routine version bumps.  For production supply-chain security,
# consider switching to digest pinning or using a verified image registry.
FROM python:3.13-slim AS builder

Expected Behavior

For production deployments, container images should use digest pinning to ensure:

Immutable base image references
Protection against tag poisoning attacks
Reproducible builds across environments

Actual Behavior

Current implementation uses tag-based pinning which allows:

Base image content to change without notice
Potential supply chain attacks through tag replacement
Non-deterministic builds

Suggested Fix

Implement digest pinning for production images: python:3.13-slim@sha256:...
Create automation to update digests when bumping versions
Add image vulnerability scanning in CI pipeline
Consider using distroless or minimal base images for production
Implement image signature verification

TDD Note

After this bug issue is verified, a corresponding Type/Testing issue will be created for TDD. The test will use tags: @tdd_issue, @tdd_issue_, and @tdd_expected_fail to verify container security properties.
