WordPress.Security.NonceVerification.Missing
Missing nonce verification
A request handler uses request data without verifying that the request was intentionally created by WordPress.
Why It Shows Up
The scan found `$_GET`, `$_POST`, or similar request data in a context where a nonce check is expected but missing.
Why It Matters
Without nonce verification, an attacker may be able to trick a logged-in user into submitting an unwanted state-changing request.
How to Fix
- Add a nonce to the form, link, AJAX request, or REST request.
- Verify it with `check_admin_referer()`, `check_ajax_referer()`, or `wp_verify_nonce()` before changing state.
- Keep capability checks separate; nonces prove intent, not permission.
