SEC515 / CLAUDE-GH-VARIABLE-DELETE-PERMISSION ​

SEC515 flags shared Claude settings when permissions.allow grants blanket GitHub variable deletion authority through gh variable delete.

Why It Matters ​

gh variable delete can remove repository, environment, or organization variables. In a shared committed settings file that is broader than most teams want to delegate by default.

Trigger Shape ​

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

Clean Cases ​

  • narrower read-only grants such as Bash(gh variable list:*)
  • settings files without blanket variable deletion access
  • fixture-like examples under test or fixture paths

Example Trigger ​

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

Safer Example ​

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

How To Fix ​

Remove shared gh variable delete permissions or replace them with narrower reviewed commands that keep variable deletion under explicit user control.
