CVE-2026-93901

Estado: AplazadaAlta (7.3)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad en función AJAX sin verificación de capacidad ni nonce (CWE-269) explotable remotamente sin autenticación. Escalada de privilegios mediante asignación de rol 'author' a cuenta preexistente, otorgando capacidades de publicación y carga de archivos.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
