CVE-2026-25925

Estado: AnalizadaAlta (7.8)—

PowerDocu contains a Windows GUI executable to perform technical documentations. Prior to 2.4.0, PowerDocu contains a critical security vulnerability in how it parses JSON files within Flow or App packages. The application blindly trusts the $type property in JSON files, allowing an attacker to instantiate arbitrary .NET objects and execute code. This vulnerability is fixed in 2.4.0.

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 + UI:R indica ejecución en cliente (abrir fichero JSON preparado). CWE-502 (deserialización insegura) + instanciación de objetos .NET = ejecución de código arbitrario.

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.
