**Checkout action is not pinned**
When the upstream `v4` tag is moved or its referenced action code is compromised, a moved or compromised `actions/checkout@v4` tag makes the workflow run unreviewed action code with repository read access and the `pull-requests: write` token, allowing it to expose repository data or alter PR metadata before the scanner runs.
Pin `actions/checkout` to a reviewed full commit SHA.

**Older scans overwrite current findings**
When a PR gets another commit while its previous scan is running and the runs finish out of order, the older run posts its summary after the newer run, leaving reviewers with stale findings and potentially hiding a newly introduced risk.
Add per-PR concurrency cancellation or verify the scanned head is still current before posting the summary.
Also at `.github/workflows/npmscan.yml:18`.

**Base-branch scans stay stale**
When a pull request's base branch changes after opening, the activity filter omits `edited`, so the workflow keeps the old lockfile comparison and findings for the new base go unreported.
Include `edited` in the `pull_request` activity types.

</code_context>
<issue_to_address>
**Base lockfile may be unavailable**
When the scanner relies on locally checked-out Git history to obtain the base lockfile, `actions/checkout@v4` uses a shallow checkout by default, and this workflow neither fetches the base ref nor requests full history before running the scanner. If `npmscan-action` uses the checkout to compare the PR base and head, it cannot read the base lockfile, so the scan reports an error or misses dependency changes.
Fetch the PR base ref or use `actions/checkout` with sufficient history before running the scanner.

</code_context>
<issue_to_address>
**PR summary comments are missing**
When the scan finds PR findings and attempts to post its summary comment, the action receives no GitHub token, so it cannot authenticate the API request to post the summary comment; findings are limited to annotations and the job summary.
Pass `github.token` to the action using its supported token input or environment variable.
</issue_to_address>Sourcery assessment
Needs a human reviewer. 5 findings to address first, and the pinned third-party action runs on pull requests with a token that can write PR metadata, so a faulty or compromised action could post or alter PR comments that remain after this workflow is reverted. The scan’s ordinary false warnings are reversible; the lasting risk is the write access granted to the action.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
Scan package.json as well as package-lock.json.
If a pull request changes only root install scripts, overrides, or resolutions in package.json, the configured lockfile remains unchanged. The pinned action then skips the scan, so it reports none of those changes. Use the action’s files input to scan both files. (raw.githubusercontent.com)

@yowainwright any reason why it's not merged? |
|
|
@yowainwright the fact that I maintain it makes you close it without explanation? I am chill tho. just wondering. maybe the npmscan is not good? |
|
@salemalem I don't see any differentiator between other similar, more recognized tools that have recourse. |
What does this PR do?
Adds a standalone
.github/workflows/npmscan.ymlthat runs npmscan-action on pull requests. It diffs the lockfile between the PR base and head and flags supply-chain red flags in the changed dependencies: newly added install scripts (preinstall/install/postinstall), repointed or swapped tarballs (URL/integrity changes), added or changedoverrides/resolutions, and known vulnerabilities in newly introduced versions.Why?
Malicious package versions usually arrive through lockfile changes in otherwise ordinary PRs, where a reviewer rarely reads the lockfile diff. This check summarises what changed so those entries stand out.
Configuration notes
mode: warnandfail-on-error: false, so it reports findings but never fails CI.contents: read(pluspull-requests: writeto post a single summary comment; on fork PRs the token is read-only, so findings go to annotations and the job summary instead).Disclosure
I maintain npmscan and npmscan-action, so I have an interest in this. If it isn't a fit for the project, please feel free to close; no hard feelings.
