Validate pre-created PR branch before privileged checkout by Copilot · Pull Request #55481 · github/gh-aw

Copilot · 2026-08-24T18:58:48Z

CodeQL flagged q.lock.yml for checking out an attacker-influenced pre-created PR branch in a privileged workflow path. The risk was that issue_comment-reachable input could flow into actions/checkout before the branch was proven to be the workflow-created branch.

Branch validation
- Adds an activation-job validation step after PR pre-creation.
- Confirms the branch matches the expected gh-aw/pre-created/<run_id>-<attempt> pattern.
- Confirms the pre-created PR head and base repositories are the workflow repository.
Safer checkout ref
- Changes generated agent and safe-output checkouts to use the deterministic workflow-owned branch ref directly, instead of the raw activation output.

ref: gh-aw/pre-created/${{ github.run_id }}-${{ github.run_attempt }}

Generated workflow update
- Regenerates .github/workflows/q.lock.yml from the updated compiler output.
- Keeps the validated branch output for safe-output metadata that still needs the branch name.

Fixes [uk-ai-resilience] Untrusted checkout of pre-created PR branch in privileged q.lock.yml workflow (Tier C, critical) #55433

@copilot update safe outputs specification using w3c spec writer

Addressed in 7174596 by updating the Safe Outputs specification with W3C-style normative requirements for pre-created PR branch provenance, validation before downstream privileged use, and deterministic checkout refs. I also updated the pull-request reference docs to match.

@copilot the user should be able to configure the branch prefix as part of the safe-outputs.create-pull-request configuration.

Verdict

REQUEST_CHANGES — this closes the original checkout injection hole, but it hard-codes a branch name that the feature already allows users to customize.

The blocking issue is a config/behavior mismatch in pre-created PR mode.

The new compiler path always checks out gh-aw/pre-created/<run_id>-<run_attempt> directly in downstream privileged jobs and the validator only accepts that exact ref. That is fine for the default case, but create-pull-request already exposes branch-prefix, and this PR now documents/validates steer as incompatible with branch-prefix instead of preserving the existing branch-prefix contract.

Right now a workflow author who configured branch naming policy cannot opt into pre-created PRs without losing that configuration surface. Either pre-created branch generation/validation needs to derive the trusted ref from configured branch-prefix, or the feature needs a much more deliberate API change than silently making the option unusable for this mode.

 const preCreatePullRequestAppTokenStepID = "pre-create-pull-request-app-token"

+func preCreatedPullRequestBranchRef() string {


This change hard-codes the trusted pre-created branch to gh-aw/pre-created/..., which breaks the existing create-pull-request.branch-prefix contract for anyone trying to use steer and branch naming policy together.

💡 Why this blocks

create-pull-request already supports branch-prefix, and the JS handler still understands it for normal PR creation. This patch makes pre-created PR mode special by forcing downstream privileged checkouts to a fixed ref and by rejecting steer + branch-prefix in validatePreCreatePullRequest().

That turns a security fix into a behavior regression: users who rely on branch naming policy cannot adopt steer at all. Either the trusted ref derivation needs to incorporate the configured prefix, or the product decision to drop branch-prefix in pre-created mode needs to be handled as an explicit API change with matching implementation/docs elsewhere.

A minimal fix would be to derive the expected trusted branch from configuration instead of returning a hard-coded literal here.

Implemented configured branch-prefix support for steer-mode pre-created branches. The compiler now derives deterministic pre-created refs from that configuration in e066cf2.

Review: Validate pre-created PR branch before privileged checkout

This is a well-structured security fix for the CodeQL finding. The two-layer defence is correct:

Validation step — validate-pre-created-pull-request checks the branch name against the deterministic gh-aw/pre-created/<run_id>-<attempt> pattern before it can flow into any downstream step.
Hardcoded ref at checkout — all actions/checkout calls now use the literal expected name instead of the activation output, so even if an attacker somehow altered the output, the checkout ignores it.

The pattern is applied consistently across all lock files. No issues found.

Skills-Based Review 🧠

Applied /diagnosing-bugs and /tdd — two issues found; one requesting changes.

📋 Key Themes & Highlights

Key Themes

Empty-branch bypass (security, line 7): If GH_AW_EXPECTED_PRE_CREATED_PULL_REQUEST_BRANCH is empty, validation silently passes and an empty trusted-branch output is emitted. Add an explicit !expectedBranch guard.
Missing null-repo test (test coverage): The ?. optional chain on line 22 handles a null head.repo correctly, but no test pins this behaviour. Add a test for the fork-deleted scenario.

Correction — inline comment #3

The concern about GitHub expression expansion in the Go compiler is a false alarm: fmt.Sprintf("...: %s\n", preCreatedPullRequestBranchRef()) emits the expression unquoted in YAML (confirmed in q.lock.yml), so ${{ github.run_id }} is correctly expanded by Actions at runtime. Disregard that comment.

Positive Highlights

✅ Validation step correctly placed after pre-creation and before the branch output is trusted by downstream jobs — good defence-in-depth ordering.
✅ pre_created_pull_request_branch output is now sourced from the validated step, not the raw pre-create output — this is the right fix for the CodeQL finding.
✅ Deterministic preCreatedPullRequestBranchRef() used for checkout ref instead of trusting the activation output — clean and correct.
✅ Test suite is well-structured (Arrange/Act/Assert) and covers the main attack scenarios.

+async function main() {
+  const expectedBranch = process.env.GH_AW_EXPECTED_PRE_CREATED_PULL_REQUEST_BRANCH || "";
+  const branch = process.env.GH_AW_PRE_CREATED_PULL_REQUEST_BRANCH || "";
+  if (branch !== expectedBranch) {


[/diagnosing-bugs] Empty expectedBranch silently bypasses validation — if GH_AW_EXPECTED_PRE_CREATED_PULL_REQUEST_BRANCH is unset or empty, both expectedBranch and branch default to "", the equality check passes, and core.setOutput("branch", "") is emitted without an error.

💡 Suggested guard

Add an explicit guard before the equality check:

if (!expectedBranch) { throw new Error("GH_AW_EXPECTED_PRE_CREATED_PULL_REQUEST_BRANCH is not set"); }

And a corresponding test:

it("rejects empty expectedBranch to prevent misconfiguration bypass", async () => { process.env.GH_AW_EXPECTED_PRE_CREATED_PULL_REQUEST_BRANCH = ""; process.env.GH_AW_PRE_CREATED_PULL_REQUEST_BRANCH = ""; const { main } = await import("./validate_pre_created_pull_request.cjs"); await expect(main()).rejects.toThrow(/not set/); });

Without this guard, a misconfigured job would accept any branch that also produces empty output.

@copilot please address this.

Added a fail-closed guard for missing expected branch metadata, with coverage, in 1fbd7c3.

+    pull_number: pullNumber,
+  });
+  const expectedRepo = `${context.repo.owner}/${context.repo.repo}`.toLowerCase();
+  if (pullRequest.head.ref !== expectedBranch || pullRequest.head.repo?.full_name?.toLowerCase() !== expectedRepo || pullRequest.base.repo?.full_name?.toLowerCase() !== expectedRepo) {


[/tdd] No test covers the case where pullRequest.head.ref matches but head.repo is null — the ?. optional chain on line 22 silently swallows this and produces undefined !== expectedRepo, which throws the right error, but there's no test to pin that behaviour. If the logic is ever refactored, a null repo could be silently accepted.

💡 Suggested test

it("rejects when head repo is null (fork-deleted scenario)", async () => { global.github.rest.pulls.get.mockResolvedValue({ data: { head: { ref: "gh-aw/pre-created/123-2", repo: null }, base: { repo: { full_name: "owner/repo" } }, }, }); const { main } = await import("./validate_pre_created_pull_request.cjs"); await expect(main()).rejects.toThrow(/does not target the expected trusted repository branch/); });

@copilot please address this.

Added coverage for a null PR head repository; it is rejected before emitting the trusted branch in 1fbd7c3.

[/diagnosing-bugs] GH_AW_EXPECTED_PRE_CREATED_PULL_REQUEST_BRANCH is set to a plain string "gh-aw/pre-created/${{ github.run_id }}-${{ github.run_attempt }}" (unexpanded) in the env: block. This means the equality check on line 7 compares the raw template literal string against the actual branch name, which will never match at runtime — validation will always fail.

The fmt.Sprintf call inserts the literal GitHub expression ${{ github.run_id }}-${{ github.run_attempt }} into the YAML, which GitHub Actions will expand before the step runs. Verify in a generated lock file that the env: block reads:

GH_AW_EXPECTED_PRE_CREATED_PULL_REQUEST_BRANCH: gh-aw/pre-created/${{ github.run_id }}-${{ github.run_attempt }}

and NOT a quoted Go string. If the value is double-quoted in YAML it will be treated as literal text by the shell and the ${{ expansion will not happen.

@copilot please address this.

The generated environment value is a GitHub Actions expression and is evaluated before the github-script step runs. Generated lockfiles contain the deterministic run-id/run-attempt ref.
