CVE-2025-8506Public exploitNetwork attack vector

Stored script execution via unencoded user records

Published Aug 3, 2025 · Updated Aug 4, 2025

Stored XSS in wx-shop at commit de1b66331368695779cfc6e4d11a64caddf8716e allows remote authenticated users to execute script. The /user/saveUser controller accepts user fields without filtering, stores them without HTML entity encoding, and returns them without output encoding. A valid backend session is required to plant the payload, and a later page view executes it in that viewer's browser.
