This repository contains a single file, 'xss.pom', which is a minimal XML file embedding a JavaScript payload. The payload, 'alert(document.location)', is a classic proof-of-concept for cross-site scripting (XSS) vulnerabilities. The file is structured as an XML document with a custom namespace, and the script is placed within a <project:script> tag. The purpose of this repository is to demonstrate how a web application that improperly handles or renders XML/HTML content could be vulnerable to XSS, allowing an attacker to execute arbitrary JavaScript in the context of a user's browser. There are no hardcoded network endpoints or product targets; the exploit is generic and intended as a demonstration of XSS risk.
