Estado: AnalizadaAlta (7)—

Joomla! Core - [20260905] - Core - Arbitrary directory deletion via cache purge action in Joomla 4.0.0-5.4.8, 6.0.0-6.1.3 -An improper validation of the cache group name allowed path traverals in the file storage of the caching layer, resulting in arbitrary directory deletions.

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.

Vector AV:N/PR:H permite explotación remota con privilegios elevados (T1210). CWE-22 path traversal causa borrado arbitrario de directorios (T1565.001 manipulación y T1490 destrucción de datos).

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.
