The vulnerability could be used to facilitate phishing attacks.\n\n## Patches\nThe issue has been fixed in n8n versions 1.123.24, 2.10.4 and 2.12.0. Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Limit workflow creation and editing permissions to fully trusted users only.\n- Disable the Form node by adding `n8n-nodes-base.form` to the `NODES_EXCLUDE` environment variable.\n- Disable the Form Trigger node by adding `n8n-nodes-base.formTrigger` to the `NODES_EXCLUDE` environment variable.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","state":0,"publishedAt":"2026-03-27T18:06:28+00:00","modifiedAt":"2026-07-11T04:11:39.8854758+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.11.0"},{"kind":"fixed","version":"2.12.0"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.0.0-rc.0"},{"kind":"fixed","version":"2.10.4"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.123.24"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:L/A:N","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-w673-8fjw-457c","https://github.com/n8n-io/n8n"],"sourceUrl":"https://github.com/advisories/GHSA-w673-8fjw-457c","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-w673-8fjw-457c","identifiers":["GHSA-w673-8fjw-457c","CVE-2026-56354"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
