CVE-2026-67688Public exploitNetwork attack vector

Stored XSS via permitted HTML file uploads

Published Aug 6, 2026 · Updated Aug 6, 2026

Stored XSS in ICS-Park Smart Park Management System 2.0 allows remote authenticated users to execute script in other users' browsers. The /dfs/upload endpoint accepts .html and .htm files because DEFAULT_ALLOWED_EXTENSION permits them, then exposes the upload directory through the /profile static-resource mapping. Any valid token is sufficient to plant a page, but script execution requires another user to open its URL and can disclose that user's session data.
