Nginx-UI: Disabled users retain full API access through previously issued bearer tokens

Description

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, a user who was disabled by an administrator can use previously issued API tokens for up to the token lifetime. In practice, disabling a compromised account does not actually terminate that user’s access, so an attacker who already stole a JWT can continue reading and modifying protected resources after the account is marked disabled. Since tokens can be used to create new accounts, it is possible the disabled user to maintain the privilege. Version 2.3.4 patches the issue.
