# Scanner: CI buildx steps run privileged: true — evaluate rootless alternative

**Severity:** low
**Domain:** CI/CD
**Labels:** security, scanner, ci-cd

## Description

`scanner/.woodpecker/development.yml:23` runs buildx with `privileged: true` for Docker-in-Docker image builds. A privileged CI runner has full access to the host kernel. If a pipeline step is compromised, it can escape the container.

## Options

1. Switch to rootless/buildkit without privileged where the runner supports it.
2. Keep privileged but pin the plugin to a digest and restrict secret exposure.
3. Run builds on an isolated runner.

## Recommendation

Evaluate a rootless buildkit setup; if infeasible, at minimum pin the plugin digest (applied via NB-41) and isolate the runner.

## Affected Files

- `scanner/.woodpecker/development.yml:23`
- `scanner/.woodpecker/production.yml`
