mall4j through 4.0 contains an unrestricted file upload vulnerability in FileController endpoints that lack authorization checks and accept arbitrary file types without validation. Attackers with any authenticated token can upload HTML or SVG files that execute scripts in administrator browsers when accessed from the local storage path, resulting in stored cross-site scripting.
