Prior to 2.4.1, POST /api/otp_enroll and POST /api/finish_passkey_register are registered outside RequireSecureSession and accept a normal authenticated session without verifying the current password. An attacker with a stolen JWT can bind an attacker-controlled TOTP secret when the victim has not already enabled TOTP, or can register an attacker-controlled passkey because that path has no equivalent existing-enrollment guard. These changes create persistent account access that can survive a password change and interfere with the legitimate user's authentication. This issue is fixed in version 2.4.1."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"0xJacky","product":"nginx-ui","versions":[{"version":"< 2.4.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-15T13:48:05.211053Z","id":"CVE-2026-84313","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-287"},{"lang":"en","value":"CWE-306"}]}],"references":[{"url":"https://github.com/0xJacky/nginx-ui/commit/23d1934099b05b2a01589b48129dc3d3159d91c2","source":"security-advisories@github.com"},{"url":"https://github.com/0xJacky/nginx-ui/releases/tag/v2.4.1","source":"security-advisories@github.com"},{"url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-gfrc-g87h-7h5w","source":"security-advisories@github.com"},{"url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-gfrc-g87h-7h5w","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
