Fix false positive numeric validation for github.event.head_commit.id by Copilot · Pull Request #16809 · github/gh-aw

Copilot · 2026-02-19T13:03:32Z

github.event.head_commit.id (a Git SHA) was incorrectly treated as a numeric field by validate_context_variables.cjs, causing push-triggered workflows to fail validation with "contains non-numeric characters".

Changes

Runtime validation (validate_context_variables.cjs): head_commit.id is correctly absent from NUMERIC_CONTEXT_PATHS — Git SHAs are hex strings, not integer IDs. Existing JS regression tests cover this.
New golden fixture (push-with-head-commit.md + .golden): End-to-end compilation test verifying that a push workflow using ${{ github.event.head_commit.id }} compiles correctly — the SHA passes through as GH_AW_GITHUB_EVENT_HEAD_COMMIT_ID without triggering numeric validation.

Users hitting this error should recompile their workflows with the latest gh-aw to pick up the fixed validate_context_variables.cjs.

<issue_title>False Positive Validation - github.event.head_commit.id contains non-numeric characters</issue_title>
<issue_description>I have followed the Quick Start guide to add the Daily Status Report to my repository (Guide here: https://github.github.com/gh-aw/setup/quick-start/)

But when the workflow runs I get an error:
Error: Context variable validation failed!

Found 1 malicious or invalid numeric field(s):

  - github.event.head_commit.id: "6d99836347ec1ac0263be4c53349b7827f67969a"
    github.event.head_commit.id contains non-numeric characters: "6d99836347ec1ac0263be4c53349b7827f67969a"

Numeric context variables (like github.event.issue.number) must be either empty or valid integers.
This validation prevents injection attacks where special text or code is hidden in numeric fields.
This is a false positive because the commit hash is expected to have non-numeric characters</issue_description>

…mit.id This adds a test that verifies: 1. A push-triggered workflow using ${{ github.event.head_commit.id }} compiles correctly 2. The compiled output passes head_commit.id as GH_AW_GITHUB_EVENT_HEAD_COMMIT_ID env var 3. The validate_context_variables.cjs step is included (which correctly does NOT validate head_commit.id as numeric) Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>

Pull request overview

Fixes a false-positive numeric validation error by ensuring github.event.head_commit.id (a Git SHA) is not treated as a numeric-only context variable, and adds an end-to-end golden test fixture covering push workflows that reference it.

Changes:

Update runtime numeric context validation to exclude github.event.head_commit.id from numeric-only checks.
Add a new wasm golden fixture (push-with-head-commit) to verify compilation succeeds when using ${{ github.event.head_commit.id }}.
Update embedded action pin data (action_pins.json) by removing a couple of entries.

pkg/workflow/data/action_pins.json:167

action_pins.json is being modified in this PR (e.g., removing the github/stale-repos@v3 alias). That change isn’t mentioned in the PR description, which currently describes only context validation + wasm golden coverage. Please update the description to justify the pin changes, or move them to a separate PR.

This issue also appears on line 183 of the same file.

    "github/stale-repos@v3.0.2": {
      "repo": "github/stale-repos",
      "version": "v3.0.2",
      "sha": "a21e55567b83cf3c3f3f9085d3038dc6cee02598"
    },

pkg/workflow/data/action_pins.json:167

Removing the github/stale-repos@v3 pin can weaken pinning for workflows that reference the major tag (@v3). In strict mode, GetActionPinWithData only falls back to semver-compatible pins when StrictMode is false, so @v3 may become effectively “unpinned” unless dynamic resolution succeeds. Consider keeping a @v3 entry (pointing at the current v3.x.y SHA), or adjusting strict-mode pin selection to allow semver-compatible fallbacks.

    "github/stale-repos@v3.0.2": {
      "repo": "github/stale-repos",
      "version": "v3.0.2",
      "sha": "a21e55567b83cf3c3f3f9085d3038dc6cee02598"
    },

pkg/workflow/data/action_pins.json:186

Similarly, removing the super-linter/super-linter@v8.2.1 pin looks unrelated to the stated goal of fixing head_commit.id numeric validation. If this cleanup is intentional, please call it out in the PR description (or split it into its own PR) so reviewers can assess action pinning impact separately.

    "super-linter/super-linter@v8.5.0": {
      "repo": "super-linter/super-linter",
      "version": "v8.5.0",
      "sha": "61abc07d755095a68f4987d1c2c3d1d64408f1f9"
