Three Dockerfiles in scripts/docker/ and scripts/e2e/ lack a USER directive, meaning all processes run as uid 0 (root). If any process is compromised, the attacker has root inside the container, making container breakout significantly easier.

Partial fix (2026-02-08): Commit 28e1a65e added USER sandbox to Dockerfile.sandbox and Dockerfile.sandbox-browser. The E2E/test Dockerfiles listed below remain unpatched.

Affected components:

• scripts/e2e/Dockerfile
• scripts/e2e/Dockerfile.qr-import
• scripts/docker/install-sh-e2e/Dockerfile
• scripts/docker/install-sh-nonroot/Dockerfile (runs as app but with NOPASSWD sudo — see related advisory)

Technical Reproduction:

1. Open each Dockerfile listed above and search for a USER directive — none found.
2. Run any of these containers: docker run --rm -it <image> id
3. Observe: returns uid=0(root).

Demonstrated Impact:

• Root inside the container enables kernel exploit attempts, volume mount abuse, and privileged syscall access.
• Test images share the same base (node:22-bookworm) as production, creating risk of accidental deployment of root-running images.

Environment: Base images node:22-bookworm and node:22-bookworm-slim default to root. Dockerfile.sandbox and Dockerfile.sandbox-browser were remediated in commit 28e1a65e; only the E2E/test images listed above remain affected.

Remediation: Add a USER directive before CMD/ENTRYPOINT in each remaining Dockerfile:

  RUN useradd --create-home --shell /bin/bash appuser

  USER appuser
