SAP NetWeaver Visual Composer does not perform sufficient input validation and output encoding on certain request data. An unauthenticated attacker could craft a malicious link containing specially crafted input. If a victim clicks the link, the injected script executes in the victim's browser within the context of the affected application. This results in a low impact on confidentiality and integrity. There is no impact on availability.
