Authorization Bypass
Reachability: External
Exploitability: Moderate
CWE: CWE-863 — Incorrect Authorization
Do not use branch-selectable workflow_dispatch for privileged workflows. workflow_dispatch requires repository write access, so this is not an anonymous or fork-based bypass. However, a write collaborator can select a branch containing a modified workflow, remove the maintain/admin check, and run jobs with actions: write and statuses: write. github.workflow_sha also refers to that selected revision.
Removing only this trigger would not close the same path because .github/workflows/community-ci.yml has a similar manual trigger, role check, status permissions, and GPU environment access. Route privileged manual requests through a trusted default-branch event or dispatcher, and apply the correction to every privileged manual workflow. A role or ref check inside a branch-selectable workflow is not a trust boundary.
The neighboring bridge does not establish a safe workflow_dispatch pattern: its github.ref == 'refs/heads/main' check applies only to its pull_request_target branch, not to workflow_dispatch, and any such check remains editable in the selected workflow revision.

Keep the Stable executor contract unchanged while moving trusted snapshot and lane tracking into a dedicated coordinator. Show Stable and Dev as explicit advisory branches and keep executor failures linked to their own runs. Signed-off-by: chaofengw <chaofengw@nvidia.com>

Use the event head SHA when an earlier snapshot step fails.
If Find the existing Stable PR snapshot fails, Capture the exact pull-request snapshot does not run, so steps.snapshot.outputs.head_sha is empty. The failure handler then exits without publishing the required failure status. Use the pull-request event head SHA as the fallback.
Proposed fix
- HEAD_SHA: ${{ steps.snapshot.outputs.head_sha }}
+ HEAD_SHA: ${{ steps.snapshot.outputs.head_sha || github.event.pull_request.head.sha }}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Background
community-ci.ymlcurrently handles trusted coordination, Stable pull-request validation, and dispatched Dev execution in one file. GitHub therefore renders jobs that do not belong to the active event as skipped nodes and collapses both tracked lanes into an opaque matrix job.Exit Criteria

8ec6e49e762aaef6ddc101b41a71b6543944280d.Not Run / Remaining Gaps
pull_request_targetcoordinator cannot execute from an unmerged PR because GitHub loads that event from the default branch. This PR is instead validated by the unchanged Stable executor and the existing default-branch coordinator; the new graph requires one post-merge PR event to verify its rendered layout.ci/developerexecutor still contains its old skipped coordinator jobs until the matching executor-only cleanup is synchronized to that branch.Contributor Self-Review
Notes For Future Readers
This is the compatibility-preserving first step toward a single-run reusable-workflow graph. After this lands, the executor-only cleanup can be synchronized to
ci/developer; Internal CI and Slack can then migrate from the legacy Stablepull_requestrun before that run is removed.Risk level
Risk rationale: the Stable executor is unchanged, but the trusted trigger moves to a new workflow file and its post-merge rendering cannot be exercised from this PR head.
