CVE-2026-15017

Estado: AplazadaAlta (8.8)—

The MDJM Event Management plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.7.8.4. This is due to missing capability checks and nonce verification in the `MDJM_Permissions::set_permissions()` and `MDJM_Employee_Manager::init()` functions, combined with the absence of server-side allow-list validation on the `employee_roles[]` and `new_role` POST parameters before they are passed to `mdjm_set_employee_role()` and `WP_User::set_role()`.

Leer descripción completaMostrar menos

This makes it possible for unauthenticated attackers to grant arbitrary MDJM capabilities — including `mdjm_employee` and `mdjm_employee_edit` — to any registered WordPress role, and subsequently leverage a subscriber-level account to escalate privileges to Administrator. `MDJM_Permissions::init()` is registered on the public WordPress `init` hook without any authentication gate, meaning the role-manipulation endpoint is reachable without any prior login.

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 plugin WordPress requiere PR:L pero acceso al endpoint público sin autenticación (init hook sin gate) + validación insuficiente en parámetros POST permite a atacante de red adyacente escalar privilegios remotamente. T1098.002 por modificación de cuentas de rol.

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.
