CI4MS Vulnerable to User Email Enumeration via Password Reset Flow

CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to version 0.28.5.0, the authentication implementation in CI4MS is vulnerable to email enumeration.

This issue has been patched in version 0.28.5.0.
