# Fix (changes systems: approval required at every step)

Follow **pyvr-navigator** rules: show each command, wait for a yes, never disable TLS
verification, never test with exploit files.

## 1. Start from the fix plan

`pyvuln-scan.py` writes `<out>-fix-plan.md` with exact commands per environment and a
checklist per project. Walk it in order. `references/playbooks.md` covers each
platform, BLOCKED Pythons and rollback.

## 2. Order

1. **Prerequisite:** where the scan warns pip < 26.2.2, upgrade pip safely first with
   python-cert-responder (`pycert-scan.py --python <env>` then its checksum-verified bootstrap).
2. **Environments (AFFECTED):** `<PY> -m pip install --upgrade "pillow>=13.0.0"`, then
   `<PY> -m pip check`. Record the old version for rollback.
3. **Projects:** bump pins and ranges to `>=13.0.0`, then re-lock with the right tool
   (`RELOCK` in the advisory: uv, poetry, pip-compile, pdm). Commit lock and manifest together.
4. **Dockerfiles:** move `FROM python:3.10` to 3.11 or newer where Pillow is used; bump
   pins; rebuild with `--pull`; redeploy.
5. **BLOCKED (Python 3.10):** plan the Python upgrade (playbooks > BLOCKED). Until it
   ships, apply the interim mitigations and record an owner and date.
6. **HTTP2Shell (Brotli):** `<PY> -m pip install --upgrade "Brotli>=1.2.1"` (and
   `"brotlicffi>=1.2.1.0"`); add `Brotli>=1.2.1` as a constraint wherever
   `urllib3[brotli]`, `httpx[brotli]` or `aiohttp[speedups]` is declared; OS copies via
   `apt`/`dnf`. Where Brotli is optional, uninstalling it is a valid fix (playbooks).
7. **Risk reducers, any time:** remove Ghostscript where EPS is not needed; uninstall
   `olefile` where FlashPix is not needed (only with approval and after checking dependents).

## 3. After each change

Re-scan that environment or project (`--python <venv>` / `--project <dir>`). Log what
changed. Finish with **pyvr-verify-close**.

## Never

- `--trusted-host`, `verify=False`, `curl -k` to get an install through.
- `--break-system-packages` on an OS Python without the user choosing it over the distro package or a venv.
- Downloading PoC code or crafted images to prove a fix.
