CVE-2026-33549

Estado: AnalizadaAlta (8.8)—

SPIP 4.4.10 through 4.4.12 before 4.4.13 allows unintended privilege assignment (of administrator privileges) during the editing of an author data structure because of STATUT mishandling.

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.

Acceso remoto autenticado (PR:L) a SPIP permitiendo asignación no intencionada de privilegios de administrador vía manipulación de estructura de datos (STATUT), resultando en escalada y acceso con credenciales elevadas.

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.
