CVE-2025-8764Public exploitNetwork attack vector

Browser script execution via unrestricted active-content upload

Published Aug 9, 2025 · Updated Aug 12, 2025

Stored XSS in linlinjava litemall 1.0 through 1.8.0 allows remote authenticated users to execute JavaScript via an uploaded file. The /wx/storage/upload handler passes the file stream, supplied content type, and original filename to storage without extension or content validation, while /wx/storage/fetch returns the file under that stored media type. An authenticated upload and a victim opening the returned file URL are required; script execution occurs in the victim's browser and can expose that browser session.
