Summary
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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
