CVE-2025-15390Public exploitNetwork attack vector

Authenticated privilege escalation via missing role checks

Published Dec 31, 2025 · Updated Dec 31, 2025

Missing authorization in PHPGurukul Small CRM 4.0 allows remote authenticated users to access administrative functions via direct URL requests. The login flow records identity but not role, while admin/edit-user.php checks authentication without validating administrative permissions. Any authenticated account can therefore reach the admin panel and read or modify user data, including user records.
