{"cve":"CVE-2026-84312","nvd":{"published":"2026-10-12T22:17:05.263","modified":"2026-10-14T12:17:18.203","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N","score":7.1},"cwes":["CWE-287","CWE-352"],"references":["https://github.com/0xJacky/nginx-ui/commit/23d1934099b05b2a01589b48129dc3d3159d91c2","https://github.com/0xJacky/nginx-ui/releases/tag/v2.4.1","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-44xr-mrhh-qm78"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-84312","score":0.00172,"percentile":0.06595,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-44xr-mrhh-qm78","url":"https://osv.dev/vulnerability/GHSA-44xr-mrhh-qm78","summary":"Nginx UI: Casdoor SSO callback uses a constant `state` parameter (login CSRF)","modified":"2026-10-19T21:40:46.634165616Z","packages":[{"ecosystem":"Go","name":"Nginx-UI","purl":"pkg:golang/Nginx-UI","ranges":["all versions"],"fixed":[]}]},{"id":"GO-2026-6773","url":"https://osv.dev/vulnerability/GO-2026-6773","summary":"Casdoor SSO callback uses a constant state parameter (login CSRF) in github.com/0xJacky/Nginx-UI","modified":"2026-10-19T21:31:37.806800912Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
