Unauthenticated administrator creation via unchecked user save

Published Jun 1, 2026 · Updated Jun 1, 2026

Improper authorization in SourceCodester Water Billing Management System 1.0 allows remote attackers to create administrator accounts. The /classes/Users.php?f=save route invokes the user-save operation without first authenticating the request or checking administrative privileges.
