Unauthenticated internal service probing via wpmdb_flush
Published Nov 18, 2025 · Updated Nov 18, 2025
Blind SSRF in WP Engine WP Migrate Lite 2.7.6 and earlier allows remote attackers to probe internal services through wpmdb_flush. The unauthenticated AJAX handler trusts intent=push and an attacker-controlled url, builds a WordPress admin-AJAX endpoint, and sends it with wp_remote_post(). No WordPress session, capability check, or nonce is required; the blind response limits direct reading, but timing and side effects reveal reachable internal services.
