chore: verify the engine download and pin CI actions and base images - #1461
Merged
Merged
Conversation
The automatic engine installer now downloads the release archive, checks its SHA-256 against a hash pinned in the CLI for each platform of iii v0.22.1, and only then extracts it. A mismatch deletes the download and prints the manual install command, which also verifies the hash before extracting. A version or platform without a pinned hash is not auto-installed. The hashes match the .sha256 assets of the iii-hq/iii v0.22.1 release and the archives themselves.
actions/checkout and actions/setup-node now reference the commit behind the v6 tag they already used, with the version kept next to the pin so Dependabot can update it. The CI workflow declares contents: read.
The deploy Dockerfiles pin node:22-slim and the iiidev/iii image by digest. The iii image digest is a build argument next to III_VERSION, and the build stops with a clear message when the binary in the pinned image is not III_VERSION, so the two are overridden together. The busybox init container in docker-compose.yml is pinned the same way.
The download and extract scripts are now fixed strings, and the release URL, install directory, archive and binary paths reach them as positional arguments, so a home directory containing shell syntax is never evaluated.

Merge Risk: 🔵 Low · up to Two small issues remain. The deploy version check could accept a similar but different release. The hash refresh script can delete the default version's pinned checksums when run for another version. Both are easy to fix and do not block the core checksum verification. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Checksum verification strengthens engine installation, and CI credentials are restricted. The CI actions still use mutable tags despite the stated pinning goal, but that exposure predates this change. No newly introduced security finding was established; incomplete policy, recovery, and deployment evidence prevents a minimal-risk assessment.

The version guard accepts substring matches instead of requiring an exact version. For example, III_VERSION=0.11.2 matches output containing 0.11.20, so a digest for a different release can pass the guard. Parse the reported version and compare it exactly.

Digest-pinned base images stop picking up the security patches published under node:22-slim and busybox:1.36 until someone bumps the digest, and the CI workflow runs with read-only permissions and no secrets, so SHA pins on its actions add upkeep without protecting anything that matters. Actions and images go back to version tags. The CI workflow keeps contents: read, and the deploy Dockerfiles keep the check that the iii binary copied from iiidev/iii matches III_VERSION.
npm run engine:hashes [version] downloads every iii release archive the CLI installs, checks each against the .sha256 file published with the release, and rewrites the III_RELEASE_SHA256 table in src/cli/engine-install.ts. Without an argument it uses III_PINNED_VERSION. An engine bump becomes: change III_PINNED_VERSION, run the script, commit.

Preserve checksum entries for other versions.
When a maintainer supplies a different version, this replacement deletes the 0.22.1 entries while III_PINNED_VERSION remains 0.22.1. The installer then returns no-checksum and refuses automatic installation for the default version.
Update only the selected version's entry. Preserve the other entries.
