GCP Container Analysis (and other scanners that read file metadata) flag CVE-2025-8869 on the bundled pip wheel that ships inside Alpine's python3 package and the python:3.11-slim image, e.g. /usr/lib/python3.12/ensurepip/_bundled/pip-25.0.1-py3-none-any.whl. Upgrading pip via `pip install --upgrade pip` updates the live dist-info but leaves this bootstrap wheel untouched, so the CVE keeps showing up. Add a `rm -f .../ensurepip/_bundled/pip-*.whl` to each affected RUN. The wheel is only used by ensurepip to bootstrap pip; once pip is installed we don't need it, and removing it in the same layer that put it there keeps it out of the final image. Verified post-push via the Container Analysis API: zero pip CVE occurrences on all 8 images. The 3 leftover pip CVEs on gcloud-cli-mcp come from the gcloud SDK's bundled Python (pip 25.3 inside /google-cloud-sdk/platform/bundledpythonunix/) and are out of scope for CVE-2025-8869. Bumped versions: - aws-api-mcp-server 2.0.4 -> 2.0.5 - multi-aws-api-mcp-server 2.0.4 -> 2.0.5 - azure-cli-mcp 1.0.5 -> 1.0.6 - gcloud-cli-mcp 1.0.13 -> 1.0.14 - gcloud-observability-mcp 1.0.4 -> 1.0.5 - gcloud-storage-mcp 1.0.4 -> 1.0.5 - kubernetes-remediation-mcp 1.0.2 -> 1.0.3 - mariadb-http-mcp-minimal 1.0.8 -> 1.0.9 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
