Detects exploitation attempts against the WordPress REST batch endpoint (CVE-2026-63030,
CVE-2026-60137) using the wp2shell PoC tool. The tool sends POST requests to the batch endpoint
via the ?rest_route=/batch/v1 query parameter, covering all attack phases from initial probe
through SQL injection and pre-auth admin creation. A 207 response confirms the endpoint is
active on the target.
