Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, GetCasdoorUri uses the configured Casdoor application name as a constant OAuth state value and CasdoorCallback does not compare the submitted state with a value bound to the initiating browser session. An unauthenticated attacker can cause a victim's browser to complete an attacker-controlled Casdoor authorization flow, and the callback can mint a Nginx UI session for the identity returned by that authorization code. This issue is fixed in version 2.4.1.
