SEC474 / MD-GH-PR-PERMISSION ​

SEC474 flags AI-native markdown frontmatter when allowed-tools or allowed_tools grants the exact token Bash(gh pr:*).

Why It Matters ​

gh pr:* bundles broad pull-request operations behind one shared permission token. Granting it directly in shared instruction frontmatter makes remote PR authority part of the default workflow instead of a narrower reviewed action.

This rule intentionally lives in the opt-in governance preset rather than the main preview lane. A shared skill may legitimately document a PR workflow, but repo-wide gh pr authority still deserves explicit review instead of reading like a headline vulnerability finding.

Trigger Shape ​

The rule triggers only when all of these are true:

  • the file is a detected AI-native markdown instruction surface
  • the path is not fixture-like
  • allowed-tools or allowed_tools contains the exact token Bash(gh pr:*)

Clean Cases ​

These stay clean:

  • more specific command examples such as Bash(gh pr diff:*)
  • unrelated GitHub CLI permissions like Bash(gh repo view)
  • fixture-like examples under test or fixture paths

Example Trigger ​

yaml
---
allowed-tools: Bash(gh pr:*), Read
---

Safer Example ​

yaml
---
allowed-tools: Bash(gh pr diff:*), Read
---

How To Fix ​

Review whether shared Bash(gh pr:*) access is really needed, or replace it with a narrower workflow-specific permission that does not grant blanket pull-request authority by default.
