Mirrors qBraid/qBraid#1343 so both repositories are graded the same way. The workflow file is byte-identical.

Adds the OpenSSF Scorecard action, which grades a repository against a set of supply-chain security checks and publishes the result publicly.

qBraid/qbraid-algorithms has no published Scorecard today, so there is currently no third-party measure of the project's security posture. After the first run there will be a score at https://api.securityscorecards.dev/projects/github.com/qBraid/qbraid-algorithms, and a badge is available if we want one in the README.

What it does

Runs weekly and on pushes to main, checks things like branch protection, signed releases, dependency pinning, token permissions, fuzzing and CI tests, uploads SARIF to code scanning, and publishes the aggregate score.

Notes

  • publish_results: true is what makes the score publicly visible. It reports only the check results, not source.
  • Expect the initial score to be middling. Several checks will fail on things already true of this repo, including the long-lived PyPI token in publish.yml and the absence of signed releases. That is the point of establishing a baseline.
  • The SARIF upload step needs GitHub code scanning enabled on this repo. If it is not, that step fails while the score still publishes — worth watching on the first run.

Summary by CodeRabbit

  • Chores
    • Added automated security analysis for branch protection changes, weekly runs, updates to the main branch, and manual launches.
    • Security results are published to code scanning and retained as an artifact for five days.

Walkthrough

Added a GitHub Actions workflow that runs OpenSSF Scorecard analysis on scheduled, push, branch-protection, and manual triggers. The workflow publishes SARIF results, retains the artifact for five days, and uploads the results to GitHub code scanning.

Changes

OpenSSF Scorecard automation

Layer / File(s) Summary
Scorecard analysis and reporting
.github/workflows/scorecard.yml
The workflow configures repository event triggers and scoped permissions. It checks out the repository without persisted credentials, runs Scorecard analysis, publishes results, retains the SARIF artifact for five days, and uploads the SARIF file to GitHub code scanning.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 16557

This PR adds automated public security scoring, but the workflow currently uses mutable action references and broad default permissions, weakening the security guarantees of the new check and increasing exposure to unexpected action changes. Merge should wait for immutable action pinning and least-privilege defaults, or require explicit owner acceptance of those bounded risks.

Addresses the review on #94.

`ossf/scorecard-action@v2` did not resolve: that repository publishes v2.3.3
through v2.4.4 and has no `v2` tag or branch, so the step could never have run.
Pinning fixes it as a side effect.

Every action is now pinned to a full commit SHA with its release in a comment.
A tag is mutable and can be repointed at other code, which is what Scorecard's
own Pinned-Dependencies check looks for. Each SHA was resolved from its upstream
repository rather than copied from the review: the suggested codeql-action SHA
was v3.37.7, superseded by v3.37.8 on 2026-08-21.

Workflow default permissions drop from `read-all` to `{}`. Job-level permissions
replace the workflow block rather than extending it, so `analysis` is unaffected,
but a job added later now starts with nothing instead of repository-wide read.

Added a concurrency group so overlapping runs from the four triggers cannot
publish SARIF out of order, and a comment recording why `actions: read` is
present -- upstream documents it for private repositories, and this repo is
public, so it is a safeguard rather than a requirement.

All four addressed in e5b76f7. One correction and one bug found while verifying.

Pin actions to SHAs — done, all four. I resolved each SHA from its upstream repository rather than copying them from the review, since pasting an unverified SHA is the supply-chain risk that pinning exists to prevent. Three matched. The fourth did not: the suggested github/codeql-action@f3712979… is v3.37.7, superseded by v3.37.8 on 2026-08-21. Pinned 42947a34… instead. Each pin carries its exact release, and I re-verified all four resolve upstream after writing the file.

This surfaced a real bug. ossf/scorecard-action@v2 does not resolve — that repo publishes v2.3.3v2.4.4 and has no v2 tag or branch. The step could never have run. Pinning to 2d114668… # v2.4.4 fixes it. Thank you for the version number; that is what led me to check.

permissions: {} — done, and the reasoning is right: job-level permissions replace the workflow block rather than extending it, so analysis is unaffected while a future job now starts with nothing instead of repo-wide read.

Concurrency group — added as suggested. Scorecard reports current repository state, so a superseded run has nothing to contribute and cancelling keeps published SARIF in trigger order.

Document actions: read — done, with a caveat worth recording. It is not in OSSF's own documented permission set (their README lists security-events, id-token, contents, issues, pull-requests, checks). It comes from the starter template, where it is documented as needed for private repositories. This repo is public, so it is very likely removable. I kept it and said so in the comment rather than dropping it, because removing a permission that some check quietly depends on would degrade the score silently and I would rather that be a deliberate decision than a side effect of a review pass.

Not addressed: the yamllint [ main ] bracket-spacing warnings. That spacing is GitHub's own template style, the repo runs no yamllint, and changing it is unrelated to this PR.

Both are private-repository permissions and this repo is public.

The only Actions API call Scorecard makes is ListWorkflowRunsByFileName, from
the Packaging and Binary-Artifacts checks. That endpoint is publicly readable:
requesting it for a public repo with no authentication at all returns 200.

Upstream's starter workflow ships `contents: read` and `actions: read` commented
out under "uncomment if installing in a private repository", and OSSF runs
Scorecard on its own public repos -- ossf/scorecard and ossf/scorecard-action --
with `security-events: write` and `id-token: write` alone. Those runs are green
and score Packaging 10, Binary-Artifacts 10 and CI-Tests 10, which is the same
evidence for dropping `contents: read`: their checkout step works without it.

Follows #94, which merged before this was raised in review on qBraid/pyqasm#412.
