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.
