CVE-2026-28201

Estado: AnalizadaAlta (8.7)—

An improper input validation, together with an overly permissive default CORS configuration in Open Notebook v1.8.1 allows remote attacker to trick a legitimate user to alter or delete arbitrary database entries via specially crafted malicious URL. Depending on the deployment, data exfiltration is also possible.

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 CVSS UI:P (interacción usuario necesaria) indica T1203. CORS permisivo + validación inadecuada permite modificación/eliminación de BD (T1565.002) y exfiltración de datos (T1020, T1213.002).

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.
