CVE-2026-89333

Estado: AplazadaMedia (6.5)—

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.0.8 via the 'student_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to disclose the email address and Tutor profile phone number of arbitrary WordPress users, including Administrators, by iterating over user IDs via the student_id parameter.

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.

IDOR en parámetro student_id permite a atacantes autenticados (PR:L) acceder a datos sensibles de usuarios arbitrarios (email, teléfono) sin validación, revelando información personal via iteración de IDs.

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.
