Injected scripts run in the browser of any user who visits the affected page, enabling session hijacking and account takeover.","solution":"Fixed in n8n versions 2.10.1, 2.9.3, and 1.123.22; users should upgrade to one of these or later. If upgrading is not immediately possible, limit workflow creation and editing permissions to fully trusted users only, and disable the Webhook node by adding `n8n-nodes-base.webhook` to the `NODES_EXCLUDE` environment variable. The source states these workarounds do not fully remediate the risk and should be used only as short-term measures.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-2p9h-rqjw-gm92","publishedAt":"2026-02-25T22:28:57.000Z","cveId":"CVE-2026-27578","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","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"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.0022,"epssCheckedAt":"2026-11-04T06:10:15.563Z","kevDateAdded":null,"advisoryAliases":["GHSA-2p9h-rqjw-gm92"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":null,"fixReleasedAt":"2026-02-25T08:17:05.836Z","daysToFix":0,"fixCheckedAt":"2026-10-29T21:40:31.393Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.7,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"n8n","fixedVersion":"1.123.22","matchedVersion":"1.123.22","fixReleasedAt":"2026-02-25T11:24:04.313Z","daysToFix":0,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:40:31.240Z"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.10.1","matchedVersion":"2.10.1","fixReleasedAt":"2026-02-25T08:17:05.836Z","daysToFix":0,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:40:31.240Z"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.9.3","matchedVersion":"2.9.3","fixReleasedAt":"2026-02-25T10:27:21.887Z","daysToFix":0,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:40:31.240Z"}]}}
