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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-84312)\n\nAffected packages:\n\n- `Nginx-UI < 1.9.10-0.20260703131214-23d1934099b0`\n\nSource: https://github.com/advisories/GHSA-44xr-mrhh-qm78","depth":"midnight","depthScore":51,"depthScoreParts":{"impact":39.1,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":221255,"id":"CVE-2026-84312","ts":1792030944491,"field":"exploit_available","old":"false","new":"true"}]}
