CVE-2025-10352Public exploitNetwork attack vector

Unauthenticated administrator creation via missing access check

Published Oct 8, 2025 · Updated Oct 8, 2025

Missing authorization in Melis Platform before 5.3.11 allows remote attackers to create administrator accounts through a crafted request. ToolUserController's addNewUserAction handled /melis/MelisCore/ToolUser/addNewUser without calling hasAccess; the patch inserts that check before processing. No authentication or user interaction is required, and a successful request grants persistent administrative access to the web application.
