CVE-2025-5288Public exploitNetwork attack vector

Unauthenticated Administrator creation via arbitrary API import

Published Jun 13, 2025 · Updated Jun 13, 2025

Privilege escalation in REST API | Custom API Generator 1.0.0 through 2.0.3 allows remote attackers to create Administrator accounts. The unauthenticated process_handler() endpoint accepts an attacker-controlled import_api URL and turns retrieved JSON author_data into a WordPress user without a capability check. No account or user interaction is required; setting post_author_role to administrator grants full control of the WordPress site.
