CVE-2026-11912

Estado: AplazadaAlta (7.5)—

The Simple File List plugin for WordPress is vulnerable to arbitrary file modification due to insufficient authorization checks in all versions up to, and including, 6.3.7. This makes it possible for unauthenticated attackers to delete and modify files on the serve. This vulnerability is exploitable even when the administrator has not enabled the AllowFrontManage setting, because the is_admin() check unconditionally short-circuits the guard before that setting is evaluated.

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.

Aplicación web WordPress expuesta sin autenticación (AV:N, PR:N, UI:N). Permite modificación/eliminación arbitraria de archivos (CWE-862, fallo de autorización). La pista sugiere T1078 pero el texto no evidencia robo de credenciales, sí manipulación de datos del servidor.

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.
