chore(ci): pin actions to immutable commit SHAs by yordis · Pull Request #4 · TrogonStack/TrogonEventStore.Plugins

yordis · 2026-09-02T18:58:54Z

Mutable tags let an upstream maintainer change what runs here after the fact, and pinning is a prerequisite for turning on the organization SHA pinning policy without taking CI down.

PR Summary

Low Risk
Workflow-only supply-chain hardening with no application or runtime behavior changes; wrong SHAs would break CI rather than silently alter product code.

Overview
Replaces mutable GitHub Action version tags with full commit SHAs in ci.yml and release.yml, with comments noting the original tag (e.g. checkout@v3 → checkout@a37ce91… # v3.7.0).

CI (vulnerability-scan and build): actions/checkout and actions/setup-dotnet are pinned. Release: the same two actions plus actions/create-release (@v1 → pinned # v1.1.4). Build, test, pack, and publish steps are unchanged; only which revision of each action runs is fixed.

Walkthrough

The CI and release workflows replace floating GitHub Actions version tags with specific commit SHAs. Workflow behavior remains unchanged.

Changes

Workflow action pinning

Layer / File(s)	Summary
Pin workflow action commits `.github/workflows/ci.yml`, `.github/workflows/release.yml`	The vulnerability-scan, build, and release jobs now use commit-pinned checkout, .NET setup, and release creation actions.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to e4e43

This change pins workflow actions, but the selected commits use runtimes no longer supported by GitHub-hosted runners, which can break vulnerability scans, builds, or release creation. Update the actions to maintained releases and repin them before merging.

Update the checkout and .NET setup action pins.

The pinned actions/checkout and actions/setup-dotnet commits in both workflows use the unsupported Node16 runtime, so vulnerability-scan, build, and release jobs may fail while loading them. Replace them with maintained releases and pin those releases to full commit SHAs.

GitHub Actions Node.js 12 actions runner removed August 2023 official documentation

💡 Result:

GitHub officially removed Node.js 12 from the Actions runner on August 14, 2023 [1]. Prior to this removal, GitHub had already initiated a deprecation process for Node.js 12, as it had been out of support since April 2022 [1][2]. As part of this transition, GitHub forced all JavaScript actions to run on Node.js 16 starting in June 2023, while initially providing an opt-out mechanism for those who needed more time to migrate [1]. The removal on August 14, 2023, finalized this process by eliminating both Node.js 12 and the associated opt-out logic from the Actions runner [1][3]. This ensured that all actions would thereafter be executed on Node.js 16 [1][3]. Maintainers were advised to update their actions to support newer Node.js versions, and users were encouraged to update their workflow dependencies to the latest versions that utilize supported Node.js runtimes [1][2].

Replace actions/create-release.

The pinned action declares the unsupported node12 runtime. GitHub removed Node.js 12 from Actions runners, so this release step can fail before it creates the draft release. Use a maintained release action with the current inputs and pin it to a full commit SHA.
