CVE-2026-8430

Estado: AplazadaCrítica (9.2)—

SPIP versions prior to 4.4.14 contain a remote code execution vulnerability in the public space that is limited to certain nginx configurations, allowing attackers to execute arbitrary code in the context of the web server. Attackers can exploit this vulnerability through specific nginx configuration scenarios to achieve code execution, and this issue is not mitigated by the SPIP security screen.

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:N/UI:N indica acceso remoto sin privilegios ni interacción; RCE en aplicación web SPIP expuesta. CWE-94 (code injection) y descripción explícita de ejecución de código arbitrario confirman T1059 como impacto.

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.
