From 2.0.0 until 2.5.0, ordinary authenticated users can access /api/nodes and /api/nodes/:id, whose responses serialize the node token field. The same token is accepted as X-Node-Secret by AuthRequired and maps the request to initUser, allowing the user to impersonate a trusted node against a reachable cluster member. This cross-node authentication bypass can expose sensitive management operations, including configuration synchronization and service restart. This issue is fixed in version 2.5.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-200","CWE-862"],"references":["https://github.com/0xJacky/nginx-ui/commit/0ecbd106c37b5143be14880c9447a66135151512","https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-32gc-wf3m-78w9","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-32gc-wf3m-78w9"],"products":["nginxui:nginx_ui"],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-107811","score":0.00435,"percentile":0.37462,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-32gc-wf3m-78w9","url":"https://osv.dev/vulnerability/GHSA-32gc-wf3m-78w9","summary":"0xJacky/nginx-ui /api/nodes Leaks Cluster Node Tokens and Allows Cross-Node Impersonation as initUser","modified":"2026-10-19T21:41:11.830882707Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":[">=1.9.10-0.20250517140552-daee3ac7ade1 <1.9.10-0.20260728091109-0ecbd106c37b"],"fixed":["1.9.10-0.20260728091109-0ecbd106c37b"]}]},{"id":"GO-2026-6702","url":"https://osv.dev/vulnerability/GO-2026-6702","summary":"0xJacky/nginx-ui /api/nodes Leaks Cluster Node Tokens and Allows Cross-Node Impersonation as initUser in github.com/0xJacky/Nginx-UI","modified":"2026-10-19T21:31:35.968158837Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":[">=1.9.10-0.20250517140552-daee3ac7ade1 <1.9.10-0.20260728091109-0ecbd106c37b"],"fixed":["1.9.10-0.20260728091109-0ecbd106c37b"]}]}],"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).
