Desbordamiento de búfer basado en pila en la función socket_connect en ext/sockets/sockets.c en PHP v5.3.3 a v5.3.6 podría permitir a atacantes dependientes de contexto ejecutar código de su elección a través de una ruta larga para un socket UNIX.

CVSS

Puntuación base: 7.5
Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 23 %
Percentil entre todas las CVEs puntuadas: 98
Fecha de la puntuación: 21/10/2026

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.
