Users should upgrade to this version or later to remediate the vulnerability.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Disable the AI Agents module by removing `agents` from the `N8N_ENABLED_MODULES` environment variable.\n- Restrict credential sharing to fully trusted users only.\n- Audit credentials with domain restrictions for unexpected sharing relationships.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","state":0,"publishedAt":"2026-07-22T21:58:31+00:00","modifiedAt":"2026-07-22T22:00:25.694701+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.28.0"},{"kind":"fixed","version":"2.28.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.27.4"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-h44j-f5r5-ph73","https://nvd.nist.gov/vuln/detail/CVE-2026-59207","https://github.com/n8n-io/n8n","https://github.com/n8n-io/n8n/releases/tag/n8n%402.27.4","https://github.com/n8n-io/n8n/releases/tag/n8n%402.28.1"],"sourceUrl":"https://github.com/advisories/GHSA-h44j-f5r5-ph73","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-h44j-f5r5-ph73","identifiers":["GHSA-h44j-f5r5-ph73","CVE-2026-59207"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
