SEC504 / CLAUDE-GH-REPO-CREATE-PERMISSION ​

SEC504 flags shared Claude settings when permissions.allow grants blanket GitHub repository-creation authority.

Why It Matters ​

gh repo create provisions new remote repositories. In shared committed settings that is a high-agency mutation capability that should usually stay narrower than a default team-wide permission grant.

Trigger Shape ​

The rule triggers only when all of these are true:

  • the file is a detected Claude settings surface
  • the path is not fixture-like
  • permissions.allow contains the exact token Bash(gh repo create:*)

Clean Cases ​

These stay clean:

  • read-only repository commands such as Bash(gh repo view:*)
  • settings files that do not grant blanket repository creation
  • fixture-like examples under test or fixture paths

Example Trigger ​

json
{
  "permissions": {
    "allow": ["Bash(gh repo create:*)", "Read(*)"]
  }
}

Safer Example ​

json
{
  "permissions": {
    "allow": ["Bash(gh repo view:*)", "Read(*)"]
  }
}

How To Fix ​

Remove shared gh repo create permissions or replace them with narrower reviewed subcommands that keep repository creation under explicit user control.
