SVG Stored XSS in LaraDashboard Media Upload

Executive Summary

LaraDashboard versions 0.9.0 through 1.2.2 are vulnerable to a stored cross-site scripting (XSS) attack via SVG file uploads. The application fails to sanitize SVG content during uploads, allowing authenticated users with media.create permission to upload malicious SVG files containing script tags. When accessed, the embedded JavaScript executes in the dashboard context.
