{"id":"CVE-2026-84312","published":"2026-10-12T22:17:05.263","lastModified":"2026-10-14T12:17:18.203","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.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N","cwes":["CWE-287","CWE-352"],"vendors":[],"products":[],"references":[{"url":"https://github.com/0xJacky/nginx-ui/commit/23d1934099b05b2a01589b48129dc3d3159d91c2","tags":[]},{"url":"https://github.com/0xJacky/nginx-ui/releases/tag/v2.4.1","tags":[]},{"url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-44xr-mrhh-qm78","tags":[]}],"exploitRefs":[{"url":"https://github.com/0xJacky/nginx-ui/commit/23d1934099b05b2a01589b48129dc3d3159d91c2","tags":[]},{"url":"https://github.com/0xJacky/nginx-ui/releases/tag/v2.4.1","tags":[]},{"url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-44xr-mrhh-qm78","tags":[]}],"hasPoc":true,"ai":null}
