Umanni RH 1.0 has a user enumeration vulnerability. This issue occurs during password recovery, where a difference in messages could allow an attacker to determine if the user is valid or not, enabling a brute force attack with valid users.

Umanni RH 1.0 does not limit the number of authentication attempts. An unauthenticated user may exploit this vulnerability to launch a brute-force authentication attack against the Login page.
