Pin Generator lets attackers create pins without permission

CVE-2025-31791 · published 1 year ago
Summary

The Pin Generator tool (versions up to 2.0.0) does not properly check who is allowed to use it, so anyone could generate pins. This could let unauthorized users obtain codes that should be restricted. Update to the latest version or apply the vendor's recommended configuration changes to enforce proper access controls.
