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:
- Open each Dockerfile listed above and search for a USER directive — none found.
- Run any of these containers: docker run --rm -it
id
- 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
