SEC408 / CLAUDE-GH-PR-PERMISSION ​

SEC408 flags shared Claude settings when permissions.allow grants blanket gh pr authority.

Why It Matters ​

gh pr:* bundles broad pull-request operations behind one shared permission token. In committed team settings that can normalize remote PR actions without forcing a narrower reviewed subcommand set.

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 pr:*)

Clean Cases ​

These stay clean:

  • more specific commands such as Bash(gh pr diff:*)
  • settings files that do not grant blanket gh pr
  • fixture-like examples under test or fixture paths

Example Trigger ​

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

Safer Example ​

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

How To Fix ​

Remove shared gh pr permissions or replace them with narrower reviewed subcommands that keep pull-request operations under explicit user control.
