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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"0xJacky","product":"nginx-ui","versions":[{"version":">= 2.0.0, < 2.5.0","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":"2026-10-14T01:56:38.587090Z","id":"CVE-2026-107811","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-200"},{"lang":"en","value":"CWE-862"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:nginxui:nginx_ui:*:*:*:*:*:*:*:*","versionStartIncluding":"2.0.0","versionEndExcluding":"2.5.0","matchCriteriaId":"0C45DE3B-CE6E-4A52-93DA-8B247A56835D"}]}]}],"references":[{"url":"https://github.com/0xJacky/nginx-ui/commit/0ecbd106c37b5143be14880c9447a66135151512","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-32gc-wf3m-78w9","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-32gc-wf3m-78w9","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Vendor Advisory"]}]}
