CVE-2026-56701

Grav before 2.0.0-beta.2 contains an XML external entity injection vulnerability in SVG file upload processing that allows authenticated attackers to read arbitrary files. The application uses simplexml_load_string without disabling external entity loading, enabling attackers to inject XXE payloads via malicious SVG files to exfiltrate sensitive data.

Summary		(es) Grav anterior a 2.0.0-beta.2 contiene una vulnerabilidad de inyección de entidad externa XML en el procesamiento de carga de archivos SVG que permite a atacantes autenticados leer archivos arbitrarios. La aplicación utiliza simplexml_load_string sin deshabilitar la carga de entidades externas, lo que permite a los atacantes inyectar cargas útiles XXE a través de archivos SVG maliciosos para exfiltrar datos sensibles.
