This repository contains a single Python script that demonstrates a proof-of-concept (PoC) exploit for a cross-site scripting (XSS) vulnerability in Kentico Xperience versions before 13.0.178 (CVE-2025-32370). The script generates a malicious SVG file containing embedded JavaScript (alert("XSS")), compresses it into a ZIP archive, and uploads it to a user-supplied endpoint (typically MultiFileUploader.ashx) on a vulnerable Kentico Xperience installation. The exploit leverages an unauthenticated file upload vector to deliver the SVG, which, if rendered by the application, will execute the JavaScript payload, demonstrating the XSS vulnerability. The repository is structured as a single Python file with clear functions for payload creation, zipping, and uploading, and is intended for security testing and demonstration purposes.
