CVE-2026-33588

Estado: AnalizadaAlta (7)—

Lack of user input validation in the file upload functionality of Open Notebook v1.8.3 allows the application user to create or modify files on 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.

AV:L sin UI:R indica escalada local. Path traversal en carga de archivos permite crear/modificar ficheros en el contenedor, consumando manipulación de datos e impacto en integridad (VI:H).

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.
