fix(ci): pin third-party actions to full commit SHAs - #29
Merged
Merged
Conversation
The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at startup — `startup_failure`, no jobs, "this workflow graph cannot be shown" — so these workflows could not run at all. This resolves each ref to the commit it currently points at and records the ref in a trailing comment, e.g. `actions/checkout@<sha> # v4`. `dtolnay/rust-toolchain` takes its toolchain from the ref itself, so those steps also gained an explicit `with: toolchain:` input; without it, a SHA ref would silently lose the channel. No behaviour is intended to change beyond the pins.

WalkthroughThe pull request replaces mutable GitHub Actions release tags with commit SHAs in five workflows. Each pinned action retains a comment identifying its release version. Workflow inputs, ordering, permissions, and other configuration remain unchanged. ChangesWorkflow action pinning
Priority: ⬇️ Low Estimated code review effort: 1 (Trivial) | ~10 minutes Change: Other Merge Risk: 🔵 Low · up to The workflows are generally mergeable, but the Scorecard step retains bounded supply-chain exposure through its nested mutable image reference. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Pin the nested Scorecard image to an immutable reference. The pinned action commit uses docker://ghcr.io/ossf/scorecard-action:v2.4.3. The outer action SHA does not make this nested image reference immutable. Use a digest-pinned or otherwise fixed execution path.
