SEC539 / MD-GH-REPO-EDIT-ALLOWED-TOOLS ​

SEC539 flags AI-native markdown frontmatter when allowed-tools grants blanket gh repo edit authority.

Why It Matters ​

gh repo edit can mutate repository settings. In shared AI-native markdown guidance that is broader than most teams want to advertise as default agent authority.

Trigger Shape ​

  • the file is an AI-native markdown surface
  • the path is not fixture-like
  • frontmatter allowed-tools or allowed_tools contains the exact token Bash(gh repo edit:*)

Clean Cases ​

  • narrower read-only grants such as Bash(gh repo view:*)
  • markdown surfaces without blanket repository edit grants
  • fixture-like examples under test or fixture paths

Example Trigger ​

yaml
---
allowed-tools:
  - Bash(gh repo edit:*)
---

Safer Example ​

yaml
---
allowed-tools:
  - Bash(gh repo view:*)
---

How To Fix ​

Remove shared gh repo edit tool grants or replace them with narrower reviewed commands that keep repository settings mutation under explicit user control.
