curl/interface.c en la librería cURL (también conocido como libcurl) en PHP 5.2.4 y 5.2.5 permite a atacantes dependientes de contexto evitar las restricciones safe_mode y open_basedir, y leer ficheros de su elección mediante una petición file:// que contiene una secuencia \x00, una vulnerabilidad diferente de CVE-2006-2563.

CVSS

Puntuación base: 5
Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 5.58 %
Percentil entre todas las CVEs puntuadas: 93
Fecha de la puntuación: 23/10/2026

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).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
