CVE-2026-105816

Estado: Pendiente de análisisAlta (8)—

Vault y Vault Enterprise no verificaban de forma coherente que las entradas almacenadas del catálogo de plugins hicieran referencia a binarios dentro del directorio de plugins configurado. Cuando Vault utiliza sellos Shamir y tiene configurado un directorio de plugins externo, un operador con privilegios capaz de restaurar una instantánea de Integrated Storage (Raft) podría ejecutar código arbitrario en el host de Vault. Esta vulnerabilidad (CVE-2026-105816) está corregida en Vault Community Edition 2.1.2 y en Vault Enterprise 2.1.2, 1.21.12, 1.20.17 y 1.19.23.

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 a red con privilegios (PR:H) mediante restauración de snapshot de almacenamiento remoto (Raft). Ejecución de código arbitrario en host Vault y lectura de datos sensatos del almacén de secretos.

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.
