CVE-2025-15416Public exploitNetwork attack vector

Stored script execution via global-variable fields

Published Jan 1, 2026 · Updated Jan 1, 2026

Stored XSS in xnx3 Wangmarket 6.0 through 6.4 allows remote authenticated users to execute scripts in other users' browsers. The /siteVar/save.do handler stores unneutralized Remark or Variable Value input during Add Global Variable and renders it on subsequent access. Valid backend credentials are required to plant the payload, and another user must later access the stored value; reported impact is limited to browser-side script execution.
