When combined with other nodes, this could lead to RCE on the n8n host.\n\n## Patches\nThe issue has been fixed in n8n versions 1.123.43, 2.20.7, and 2.22.1. 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 XML node by adding `n8n-nodes-base.xml` 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.\n\n---\nn8n has adopted CVSS 4.0 as primary score for all security advisories. CVSS 3.1 vector strings are provided for backwards compatibility.\n\nCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","state":0,"publishedAt":"2026-05-14T16:17:49+00:00","modifiedAt":"2026-07-20T13:45:34.8708936+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.123.43"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.21.0"},{"kind":"fixed","version":"2.22.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.0.0-rc.0"},{"kind":"fixed","version":"2.20.7"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"CRITICAL"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-wrwr-h859-xh2r","https://nvd.nist.gov/vuln/detail/CVE-2026-44791","https://github.com/advisories/GHSA-hqr4-h3xv-9m3r","https://github.com/n8n-io/n8n"],"sourceUrl":"https://github.com/advisories/GHSA-wrwr-h859-xh2r","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-wrwr-h859-xh2r","identifiers":["GHSA-wrwr-h859-xh2r","CVE-2026-44791"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
