CVE-2026-33589

Estado: AnalizadaAlta (8.2)—

Lack of user input validation in the file upload functionality of Open Notebook v1.8.3 allows the application user to access local files content from the docker container via path traversal.

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:L sin UI:R indica acceso local sin interacción del usuario; path traversal en carga de archivos permite lectura de archivos locales del contenedor (CWE-20: falta validación de entrada).

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.
