CVE-2025-66342

Estado: AnalizadaAlta (7.8)—

A type confusion vulnerability exists in the EMF functionality of Canva Affinity. A specially crafted EMF file can trigger this vulnerability, which can lead to memory corruption and result in arbitrary code execution.

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 AV:L UI:R indica explotación en cliente: archivo EMF malformado abre en Affinity. Type confusion causa corrupción de memoria y 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.
