SEC484 / CLAUDE-GIT-APPLY-PERMISSION ​

SEC484 flags shared Claude settings when permissions.allow grants blanket git apply authority.

Why It Matters ​

git apply can apply arbitrary patches to the working tree or index. Granting Bash(git apply:*) in shared Claude settings makes broad patch-application authority a default shared permission.

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(git apply:*)

Clean Cases ​

These stay clean:

  • more specific commands such as Bash(git apply patch.diff)
  • settings files that do not grant blanket git apply
  • fixture-like examples under test or fixture paths

Example Trigger ​

json
{
  "permissions": {
    "allow": ["Bash(git apply:*)", "Read(*)"]
  }
}

Safer Example ​

json
{
  "permissions": {
    "allow": ["Bash(git apply patch.diff)", "Read(*)"]
  }
}

How To Fix ​

Remove shared git apply permissions or replace them with a narrower reviewed workflow that keeps patch application under explicit user control.
