Vulnerabilidad · Publicado 25/09/2026
El plugin Optima Express IDX para WordPress contiene una vulnerabilidad de escalación de privilegios (CVSS 7.3) que permite a atacantes no autenticados ejecutar funciones administrativas a través de la acción AJAX `wp_ajax_nopriv_ihf_clear_cache`. La vulnerabilidad afecta todas las versiones hasta la 8.7.5 y expone sitios inmobiliarios y portales empresariales en México y LATAM que utilizan este plugin. Un atacante podría comprometer credenciales de autenticación y obtener acceso administrativo completo.
The Optima Express IDX plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 8.7.5. This is due to the `provisionBlogCredentials()` function in `iHomefinderAdmin.php` being reachable via the `wp_ajax_nopriv_ihf_clear_cache` AJAX action — through the call chain `iHomefinderAjaxHandler::clearCache()` → `activateAuthenticationToken()` → `getAuthenticationInfo()` → `provisionBlogCredentials()` — with no capability check, nonce verification, or ownership validation, and the function unconditionally calling `$user->set_role('author')` on whichever WordPress account matches the hard-coded login `optima-express` via `get_user_by('login', 'optima-express')`. This makes it possible for unauthenticated attackers to escalate a pre-registered `optima-express` account to the Author role, gaining `publish_posts`, `upload_files`, and `edit_published_posts` capabilities, including access to the plugin's own `/wp-json/optima-express/v1/blog-post` REST endpoint. Exploitation requires open user registration to be enabled on the target site, and the attacker must register the `optima-express` username before the plugin has had the opportunity to provision that login for its own integration account.
