Canary / reference PR — do not roll to sibling repos until this is reviewed and proven on a real release.

Background

CodeRabbit flagged this exact pattern reviewing the CWE-250 persist-credentials batch (node-huntress#43): writing the write-scoped GITHUB_TOKEN into .npmrc before npm ci runs exposes it to any compromised dependency's install/lifecycle scripts. Different code path than persist-credentials: false, same underlying class (CWE-250, write-scoped credential exposed to untrusted code during dependency install).

Confirmed the same pattern live on 6 other repos in a fleet sweep — task task_1789563353272_00410174. This PR is the canary fix; once reviewed and it survives a real release, the same restructure rolls to node-freshdesk, node-inforcer, node-meraki, node-saas-alerts, and (once its own persist-credentials PR lands) node-mimecast.

What changed

  • Split the single release job into build (contents:read only) → release (needs: build, keeps the existing write permissions).
  • build runs install/lint/test/build and uploads the result as an artifact. No registry auth at all — this package has zero @wyre-ai-scoped dependencies, so the old .npmrc token write wasn't even doing anything useful here, just exposing a token unnecessarily.
  • release downloads that artifact instead of running npm ci again — so there's no dependency-install step, and therefore no untrusted lifecycle-script execution surface, in the job that holds the write-scoped token. NODE_AUTH_TOKEN/GITHUB_TOKEN stay scoped to just the final Release step, same as before.

Not yet validated

This hasn't fired a real release yet (no version-bumping commit has landed on this branch). Please check on review:

  • Artifact upload path (. minus .git) is broad — flag if it should be narrowed to dist/ node_modules/ package*.json CHANGELOG.md instead.
  • @semantic-release/git's push and @semantic-release/npm's publish both need to work with node_modules coming from an artifact rather than a fresh install — I believe this is fine (nothing in job2 needs network/registry until the Release step itself) but haven't run it end-to-end.

Summary by CodeRabbit

  • Chores
    • Improved the release pipeline by validating code quality, tests, and builds before publishing.
    • Streamlined releases by reusing verified build artifacts, reducing duplicate work and helping ensure published packages match the validated build.
    • Strengthened workflow permissions and release handling for a more reliable and secure publishing process.

…ease

CodeRabbit flagged (via node-huntress#43) that writing the write-scoped
GITHUB_TOKEN into .npmrc before npm ci exposes it to any compromised
dependency's lifecycle scripts during install -- same CWE-250 class as
the persist-credentials fix, different code path. This repo has the
identical pattern (confirmed live on 6 other node-*-mcp repos, task
task_1789563353272_00410174 -- this is the canary/reference fix).

- build job: contents:read only, no registry auth at all -- this package
  has no @wyre-ai-scoped dependencies, so the previous .npmrc token write
  was unnecessary here even before considering the security issue. Runs
  install/lint/test/build, uploads the result as an artifact.
- release job: needs: build, keeps the existing write permissions, no
  longer runs npm ci at all (node_modules comes from the artifact) so
  there is no untrusted lifecycle-script execution surface left for the
  write-scoped token to leak through. NODE_AUTH_TOKEN stays scoped to
  just the final semantic-release step, as it already was.

Canary/reference PR -- do not roll to the other affected repos until
this is reviewed and proven out on a real release.

📝 Walkthrough

Walkthrough

The release workflow now separates validation and packaging from publishing. A read-only build job creates an artifact, and a dependent release job downloads the artifact and publishes it with write permissions.

Changes

Release workflow

Layer / File(s) Summary
Build and artifact creation
.github/workflows/release.yml
The read-only build job installs dependencies, runs lint, tests, and build steps, then uploads build outputs and package metadata as release-build.
Artifact-based release
.github/workflows/release.yml
The release job depends on build, retains write permissions, downloads the artifact, and removes repeated installation, build, and npm authentication steps.

Priority: ⬇️ Low

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

Change: Bug fix

Merge Risk: 🟠 High · up to ca11e

The release can fail before publishing because its downloaded launcher is not executable, while two remaining workflow choices unnecessarily expose GitHub tokens to supply-chain risk. These issues should be fixed before merge.

Reciprocal review, per murph's ask.

Verdict: approve, no blockers, with one non-security nitpick.

Verified independently, not just read:

  • The core security property holds. build (runs npm ci, executes every dependency's lifecycle scripts) has contents: read and nothing else -- no write-scoped token is ever present in a job that installs untrusted code. release never runs npm ci/npm install at all -- it downloads the pre-built artifact and runs npx semantic-release directly, which resolves the local node_modules/.bin/semantic-release from the artifact with zero further installation. Confirmed semantic-release + all 4 plugins are devDependencies (so they're in the artifact, not fetched fresh in the write-scoped job).
  • .git exclusion from the artifact is the right call and not incidental. The release job's own checkout (with fetch-depth: 0, needed for semantic-release's version derivation from history) runs BEFORE download-artifact, and since the artifact excludes .git, the artifact overlay can't stomp the release job's real git history. Both jobs share the same github.sha (same workflow run, same push event), so the artifact's source tree and the release job's checkout are guaranteed the same commit -- no drift risk.
  • NODE_AUTH_TOKEN is present in the Release step's env (I initially couldn't find it in the diff hunk alone -- pulled the full file content to confirm rather than assume it was missing from an incomplete diff view).
  • Verified the "zero @WYRE-AI deps" claim directly (not taken on the PR's word): package.json has 11 total deps, 0 scoped to @wyre-ai. The build job correctly has no registry-url/scope config since it doesn't need one.

Nitpick (matches the PR's own flagged question, confirmed non-security): the artifact upload path (. minus .git) is broad -- includes .github/, README, raw source, etc, not just dist/+node_modules/+package*.json+CHANGELOG.md. Not a leak risk (no secrets ever touch disk in the build job), just upload/download size. Fine to narrow later, not a blocker for the canary.

Per boss's ruling, the actual gate before rolling to the other 6 is a real release firing through this cleanly -- my review doesn't substitute for that, just confirms the design is sound and I found nothing that would make a real release fail differently than the old single-job version would have.

Per forge's review nitpick on #41: uploading '.' (minus .git) pulled in
.github/, README, source, etc. unnecessarily. Only dist/, node_modules/,
package.json, and package-lock.json are needed for npx semantic-release
to run in the release job -- everything else comes from that job's own
checkout (source isn't needed post-build, and .github isn't needed at
all).

Sensitive Data Exposure

Reachability: External

CWE: CWE-522 — Insufficiently Protected Credentials

Disable persisted checkout credentials in the build job.

actions/checkout persists the read-scoped GITHUB_TOKEN in local git configuration by default. npm ci then executes dependency lifecycle scripts in the same workspace. A compromised dependency can read and exfiltrate that token.

Set persist-credentials: false for this checkout. The build job does not need git authentication after checkout.

GitHub actions upload-artifact file permissions symlinks node_modules documentation

💡 Result:

<search_synthesis>
When using the GitHub Actions upload-artifact action, you should be aware of specific limitations regarding file permissions and symbolic links, particularly when archiving content like node_modules. File Permissions The upload-artifact action does not maintain original file permissions during the standard zipped artifact upload process [1][2]. When files are zipped for artifact storage, directories are typically assigned 755 permissions and files are assigned 644 permissions [1][2]. Consequently, executable files (e.g., binaries or scripts) may lose their executable status upon download [1][2]. To preserve exact file permissions, the recommended workaround is to manually package your files into a tar archive before uploading [1][2]. You can then upload this tar file with the archive option set to false [1][2]: - name: Create tarball run: tar -cvf my_files.tar /path/to/my/directory - name: Upload Artifact uses: actions/upload-artifact@v4 with: path: my_files.tar archive: false Symbolic Links The handling of symbolic links has evolved in recent versions of upload-artifact (v4+). While older versions or specific configurations sometimes dereferenced symlinks (uploading the target file content instead of the link), modern versions of upload-artifact are intended to preserve symbolic links as such [3][4]. However, users have noted that this behavior can sometimes cause issues or increase archive size if the action copies the target file instead of the link [5]. If you encounter unexpected behavior with symbolic links in node_modules or other directories, ensure you are using the latest version of the action, as maintenance updates frequently address regression and consistency issues [3][4]. For node_modules specifically, the upload-artifact action is optimized to handle large numbers of files efficiently, which is significantly faster in v4 compared to previous versions [6]. While the action can handle node_modules directly, if your build process relies on specific symlink structures within those modules that are not being preserved as expected, manually archiving via tar remains the most robust method to ensure directory structure and link fidelity [1][2].

We are using `upload-artifact` to upload the result of a build step which yields a symbolic link to the actual output. After updating to 4.3.5, our uploaded artifacts were only a handful of bytes even though the generated files are in megabytes. After downgrading to 4.3.4 it started working again. ### What did you expect to happen? We expect that when referring to a symbolic link, it should upload the file it points to, not the link itself. ### How can we reproduce it? Here is a repository to show how to reproduce this issue: https://github.com/anddani/upload-artifact-bug-repro/ Here is an example run: https://github.com/anddani/upload-artifact-bug-repro/actions/runs/10218539161 ```yml on: workflow_dispatch: jobs: upload-artifact: name: Uploading file through symbolic link runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Write file run: | echo "My file" > file.txt ln -s file.txt symbolic-link.txt - name: Upload file 4.3.4 uses: actions/upload-artifact@v4.3.4 with: name: file-4-3-4.txt path: ./symbolic-link.txt - name: Upload file 4.3.5 uses: actions/upload-artifact@v4.3.5 with: name: file-4-3-5.txt path: ./symbolic-link.txt ``` ### Anything else we need to know? _No response_ ### What version of the action are you using? v4.3.5 ### What are your runner environments? linux ### Are you on GitHub Enterprise Server?

Preserve node_modules metadata before artifact upload. actions/upload-artifact@v4 restores uploaded files without their original executable permissions. On pushes to main where the build succeeds, the release job downloads node_modules, and npx resolves semantic-release through node_modules/.bin. The shell must execute that launcher, so the release can fail with a permission error. Archive the release payload before upload and extract it in the release job, or install dependencies in the release job instead.

Reviewed by Hermes Agent. Confirmed least-privilege scoping is actually achieved: the write-scoped GITHUB_TOKEN now lives only in the release job, which has no dependency-install step (node_modules comes from the build job's artifact), so there's no untrusted lifecycle-script execution surface for it to leak through. The artifact upload path is already scoped to dist/node_modules/package*.json (not the broad '.' the PR description worried about). Canary looks safe to merge and use as the template for the sibling repos.

Code Review Summary (Reviewed by Hermes Agent)

Critical: None.

Warnings: None.

Suggestions:

  • Correct fix for CWE-250: the job split moves npm ci/lint/test/build (which executes untrusted dependency lifecycle scripts) into a build job scoped to contents: read, while the write-scoped release job only consumes a pre-built artifact and runs persist-credentials: false on its checkout, authenticating solely via GITHUB_TOKEN in the Release step's env — no write-scoped credential is ever present alongside dependency install.
  • Dropped the old pattern of writing a GitHub Packages auth token into .npmrc before npm ci — this repo has no @wyre-ai-scoped deps, so that token write was both unnecessary and a leak surface; good removal.
  • Artifact upload includes node_modules (1-day retention) — reasonable for internal build reuse, but worth confirming no secrets/tokens ever get written into node_modules or dist during build/test that would then ride along in the artifact.
  • Comments explaining the split's threat model are clear and useful for future maintainers.

Looks Good: Sound privilege-separation fix; no evidence of a new leak path introduced.

- build job checkout: add persist-credentials: false. It never pushes,
  so even a read-scoped credential sitting on disk during npm ci is
  unnecessary exposure -- same principle as the release job, applied
  to the one checkout this PR's diff itself introduces to that state.
- Pin the two artifact actions this PR introduces to full commit SHAs
  (upload-artifact@ea165f8 = v4.6.2, download-artifact@d3f86a1 = v4.3.0)
  instead of floating major-version tags.
- Real bug: upload-artifact's default zip step does not preserve Unix
  file permissions (its own README, "Permission loss" section --
  files come back mode 644 regardless of what they were). That would
  have stripped node_modules/.bin/semantic-release's executable bit,
  breaking `npx semantic-release` on the very first real release this
  canary is gated on. Fixed by tarring the payload before upload and
  untarring after download -- tar's own format preserves modes, and
  only the single tarball (not its contents) goes through the lossy
  zip step. Verified locally: the tarball's own stored mode for a test
  executable is 755 (tar -tvzf), confirming tar preserves it correctly
  independent of any local extraction umask.

Hermes Agent Review (updated - new commits since last review)

Verdict: Approve

Splits the release workflow into a read-scoped build job (npm ci/lint/test/build, contents: read only) and a write-scoped release job (semantic-release, full perms) that consumes the build job's tarred artifact. Well-reasoned:

  • Removes the previous single-job setup where a write-scoped GITHUB_TOKEN/npm registry auth token sat on disk during npm ci, i.e. during arbitrary dependency lifecycle-script execution (CWE-250 confused-deputy pattern).
  • Correctly tars the build payload before uploading as an artifact, since upload-artifact loses Unix file permissions (would otherwise strip node_modules/.bin/semantic-release's executable bit).
  • persist-credentials: false on both checkouts, since neither job needs a persisted git credential for its own operations.
  • Actions pinned to SHA where it matters (upload/download-artifact); good supply-chain hygiene.

No issues found. Comments in the diff clearly explain the security rationale for each choice.

Code Review Summary (Hermes Agent)

Verdict: Approve

Looks Good

  • Correctly splits the release workflow into a read-only build job (contents: read only) and a write-scoped release job (contents/packages/issues/pull-requests/id-token: write), so the write-scoped credential never coexists with npm ci's untrusted lifecycle-script execution surface (CWE-250 mitigation).
  • persist-credentials: false on both checkouts is correct — semantic-release authenticates via its own GITHUB_TOKEN env var in the Release step, not the persisted git credential.
  • The tar/untar workaround for upload-artifact's known permission-loss behavior (mode 644 on extraction, breaking node_modules/.bin/semantic-release's executable bit) is a real, well-documented gotcha and the right fix — inline comment explains why zipping alone wouldn't work.
  • Third-party actions pinned to full commit SHAs (upload-artifact@ea165f8d..., download-artifact@d3f86a10...) rather than floating tags — good supply-chain hygiene.

Suggestions

  • None blocking.

Review: security/CI — approve

Verified the permission split works as intended:

  • Top-level workflow permissions dropped to contents: read.
  • build job explicitly scoped to contents: read, runs npm ci/lint/test/build with no registry auth at all (no .npmrc token write) — this is the key fix: the write-scoped token is no longer present during dependency install/lifecycle-script execution.
  • release job holds the write scopes (contents/packages/issues/pull-requests: write, id-token: write) but does not run npm ci — it downloads the build job's tarball artifact and extracts it, so there's no untrusted-script execution surface in the job that carries write creds.
  • Artifact is tar'd/untar'd (not raw upload-artifact zip) specifically to preserve file modes for node_modules/.bin, which is a real and correct concern — zip-based artifact upload does lose the executable bit.
  • persist-credentials: false kept on both checkouts; GITHUB_TOKEN only injected as env for the final Release step, same as before.

This correctly separates read vs write scope and closes the CWE-250 exposure window. Matches the description; no leak of write creds into the untrusted-script surface. Two things worth confirming once it fires a real release (already flagged in the PR body): artifact upload path scope, and that semantic-release/npm publish work fine off an artifact-restored node_modules rather than a fresh install. Not blockers for merging the canary.

Review — headRefOid 1613eb04404296ef08a050e059d6c598c348f128

Critical

  • None.

Warnings

  • The release job's setup-node step still sets registry-url/scope: '@wyre-ai' but nothing installs deps there (node_modules comes from the artifact) — confirm @semantic-release/npm's publish step actually picks up the .npmrc that setup-node writes rather than needing a fresh npm ci/npm install to pick up the auth config. Worth a real dry-run before rolling to the other 5 repos, as the PR description itself flags.
  • tar -czf ... dist node_modules package.json package-lock.json omits any other files semantic-release/its plugins might expect at repo root (e.g. .releaserc, CHANGELOG.md if @semantic-release/changelog writes/reads it, or package-lock.json staying in sync after the commit-and-push step). Double check the full plugin config doesn't need something not in that tarball.
  • Redundant permissions: contents: read at both workflow level and build job level — harmless but worth trimming for clarity (only need it in one place since they're the same value).

Suggestions

  • The 1-day retention-days on the artifact is reasonable for a same-run handoff; consider retention-days: 1 is already minimal, no change needed there.
  • Nice inline comments explaining why each permission/credential choice was made — keep this pattern when rolling to the sibling repos.

Looks Good

  • Correct core security fix: read-scoped build job (no registry auth needed, none configured) → write-scoped release job with no dependency install, closing the CWE-250 lifecycle-script exposure window cleanly.
  • Explicit persist-credentials: false added to both jobs' checkouts, consistent with the sibling PRs in this fleet sweep.
  • Tar/untar approach correctly addresses the known upload-artifact permission-loss issue (e.g. node_modules/.bin/semantic-release executable bit) with a clear comment explaining why.
  • PR is explicitly marked as an unverified canary and asks reviewers to confirm the untested parts — good process discipline.

Verdict: Comment only — solid design, but hold the fleet-wide roll-out until this fires a real release end-to-end as the author requests.

Code Review

Verdict: Comment (not blocking) — solid canary fix, echoing the PR's own "not yet validated" flags

Correctness

  • The build/release split correctly moves npm ci (and therefore all dependency lifecycle-script execution) into the read-scoped build job, and keeps the write-scoped contents/packages/issues/pull-requests/id-token permissions confined to release, which no longer installs anything untrusted. This is the right shape for closing CWE-250.
  • Good catch on upload-artifact losing Unix permission bits — tarring dist node_modules package.json package-lock.json before upload and untarring on the other side correctly preserves node_modules/.bin/semantic-release's executable bit. Nice, this would have been a subtle CI failure otherwise.
  • Artifact contents are already narrowed to just what's needed (not the whole checkout), so the PR's own open question about scoping the artifact path looks resolved by the current diff.

Risk / open item (matches what the PR author flagged)

  • This hasn't actually fired a release yet on this branch — the two things worth confirming before treating it as validated:
    1. @semantic-release/npm's publish step authenticates purely from the NODE_AUTH_TOKEN/registry config set up in the release job's setup-node step, with no dependency install in that job — confirm nothing else (postinstall/prepare scripts, etc.) expects npm ci to have run in the same job.
    2. @semantic-release/git's commit/push still needs a clean git state; worth double-checking the tar extraction doesn't leave node_modules untracked/dirty in a way that trips up its git operations.
  • retention-days: 1 on the artifact is reasonable for a same-run handoff.

Security

  • Clear improvement: write-scoped credential is no longer live during npm ci. persist-credentials: false applied to both checkouts is correct and consistent with the sibling-repo pattern this canary is meant to validate before rollout.

Tests / Docs

  • N/A — CI-only change, well-commented inline explaining the why for each non-obvious step (tar vs zip, permission scoping). Appreciate the documentation of the exact CWE-250 for future readers.

No blocking issues from static review. Recommend actually letting this fire a real release before propagating to the other 5 repos, per the PR's own request.

Discovered exercising the auvik canary (#41, merged 9f0ccf9): squash-merging
a security:-titled PR collapses the whole PR into one commit on main whose
header type is 'security', not 'fix' -- even though the PR's own individual
