SAP NetWeaver Visual Composer is a web-based development tool used within SAP's enterprise application platform. An unauthenticated attacker can craft a malicious link that injects JavaScript code; when a victim clicks the link, the code executes in their browser with access to their session and data within the application. This enables attackers to steal sensitive information or perform actions on behalf of the victim.
