{"cve":"CVE-2026-33031","nvd":{"published":"2026-04-20T21:16:32.783","modified":"2026-10-26T22:10:00.163","status":"Analyzed","description":"Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, a user who was disabled by an administrator can use previously issued API tokens for up to the token lifetime. In practice, disabling a compromised account does not actually terminate that user’s access, so an attacker who already stole a JWT can continue reading and modifying protected resources after the account is marked disabled. Since tokens can be used to create new accounts, it is possible the disabled user to maintain the privilege. Version 2.3.4 patches the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-284","CWE-863"],"references":["https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-x234-x5vq-cc2v"],"products":["nginxui:nginx_ui"],"source":"nvd","synced_at":"2026-10-26T22:26:44.656832877+00:00"},"epss":{"cve":"CVE-2026-33031","score":0.00274,"percentile":0.19669,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-x234-x5vq-cc2v","url":"https://osv.dev/vulnerability/GHSA-x234-x5vq-cc2v","summary":"Nginx-UI: Disabled users retain full API access through previously issued bearer tokens","modified":"2026-06-25T23:11:41.135424368Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["<1.9.10-0.20260314152518-7b66578adb47"],"fixed":["1.9.10-0.20260314152518-7b66578adb47"]}]},{"id":"GO-2026-5733","url":"https://osv.dev/vulnerability/GO-2026-5733","summary":"Nginx-UI: Disabled users retain full API access through previously issued bearer tokens in github.com/0xJacky/Nginx-UI","modified":"2026-06-25T23:01:42.666562964Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["<1.9.10-0.20260314152518-7b66578adb47"],"fixed":["1.9.10-0.20260314152518-7b66578adb47"]}]}],"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).
