When that configuration is used, the authentication check can be circumvented. The issue requires this non-default configuration to be in place.","solution":"The issue has been fixed in n8n versions 2.10.1, 2.9.3, and 1.123.22; users should upgrade to one of these versions or later. If upgrading is not immediately possible, limit workflow creation and editing permissions to fully trusted users only, use a different authentication method for the Chat Trigger node, or restrict network access to the webhook endpoint to trusted origins. These workarounds do not fully remediate the risk and should only be short-term measures.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-jh8h-6c9q-7gmw","publishedAt":"2026-02-26T22:45:41.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":["n8n@>= 2.10.0, < 2.10.1 (fixed: 2.10.1)","n8n@>= 2.0.0, < 2.9.3 (fixed: 2.9.3)","n8n@< 1.123.22 (fixed: 1.123.22)"],"affectedPackageNames":["n8n"],"affectedPackageRefs":["npm:n8n"],"affectedVendors":[],"affectedVendorsRaw":["n8n","n8n Chat Trigger node"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":["GHSA-jh8h-6c9q-7gmw"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":null,"fixReleasedAt":"2026-02-25T08:17:05.836Z","daysToFix":-1,"fixCheckedAt":"2026-10-29T21:40:28.093Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.8,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"n8n","fixedVersion":"2.9.3","matchedVersion":"2.9.3","fixReleasedAt":"2026-02-25T10:27:21.887Z","daysToFix":-1,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:40:27.942Z"},{"ecosystem":"npm","name":"n8n","fixedVersion":"1.123.22","matchedVersion":"1.123.22","fixReleasedAt":"2026-02-25T11:24:04.313Z","daysToFix":-1,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:40:27.942Z"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.10.1","matchedVersion":"2.10.1","fixReleasedAt":"2026-02-25T08:17:05.836Z","daysToFix":-1,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:40:27.942Z"}]}}
