CVE-2026-85697

Estado: AplazadaAlta (7.1)—

Documenso 2.17.0 contains an access control vulnerability in the PDF-serving endpoint that fails to validate document visibility settings. Attackers with low privileges can read restricted documents within their team or cross-tenant by leveraging missing ownership validation on document data identifiers.

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:N + PR:L indica acceso remoto con privilegios bajos; fallo de validación permite leer documentos restringidos (T1005). CWE-863 es control de acceso deficiente.

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.
