CVE-2026-94045Public exploitNetwork attack vector

Stored XSS via polyglot image filename suffix

Published Sep 20, 2026 · Updated Sep 20, 2026

Stored cross-site scripting in newbee-ltd newbee-mall 1.0 allows remote authenticated users to run script in a victim's browser. UploadController accepts a polyglot image because ImageIO.read returns an image, then preserves its attacker-controlled suffix and serves the stored file under /upload/. Administrative access is required to upload the file, and script execution requires another user to open the resulting upload URL.
