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.","state":0,"publishedAt":"2026-10-09T15:36:18.662+00:00","modifiedAt":"2026-10-14T01:57:18.316+00:00","affected":[{"ecosystem":"Vendor product","name":"nginx-ui","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"0xJacky\",\n                    \"product\": \"nginx-ui\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.0.0, < 2.5.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-32gc-wf3m-78w9","https://github.com/0xJacky/nginx-ui/commit/0ecbd106c37b5143be14880c9447a66135151512","https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107811","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107811","identifiers":["CVE-2026-107811"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
