high Security checks software dependencies conf 0.90 ✓ Repobility Dockerfile FROM `ubuntu:22.04` not pinned by digest

`FROM ubuntu:22.04` resolves the tag at build time. The registry CAN re-push a different image for the same tag, so every build is potentially different. Production images should pin to `image@sha256:...` for reproducibility + supply-chain integrity.

COPY . or ADD . is safer when .dockerignore excludes secrets, git history, keys, and generated artifacts.

When dependency installation comes after COPY ., any source change invalidates the dependency layer and makes Docker rebuild much more slowly.

`uses: Vampire/setup-wsl@v6` is 1 major version(s) behind the latest published release v7.0.0. Old action majors run on deprecated runner images / Node versions and miss upstream fixes. This is the exact 'outdated GitHub Action' class Dependabot raises — and which Repobility had no coverage for.

Agent helper projects often publish one-line installers. `curl | sh` style commands are convenient, but they bypass review unless the script is pinned, signed, or checksum-verified.

The scanner did not find any standard auth library (JWT, OAuth, NextAuth, Auth0, etc.). Either auth lives in custom code, in a separate service, or is missing.
