newbee-ltd newbee-mall up to 1.0.0 Goods Save Endpoint UploadController.java goodsName cross site scripting

Summaryinfo

A vulnerability classified as problematic was found in newbee-ltd newbee-mall up to 1.0.0. The affected element is an unknown function of the file controller/common/UploadController.java of the component Goods Save Endpoint. Executing a manipulation of the argument goodsName can lead to cross site scripting. The identification of this vulnerability is CVE-2026-94045. The attack may be launched remotely. Furthermore, there is an exploit available. ImageIO.read() is a format-agnostic read - it returns non-null for a polyglot PNG|<img onerror> payload, which is exactly why the "image-only" guard is bypassable; the attacker-controlled suffix + /upload/** static mapping is what turns the upload into persisted XSS rather than a one-shot. The project was informed of the problem early through an issue report but has not responded yet.
