With SSRF protection disabled by default (`N8N_SSRF_PROTECTION_ENABLED=false`), this let an authenticated user make the n8n server issue HTTP requests to arbitrary internal targets.\n\n## Patches\nThe issue has been fixed in n8n versions 1.123.64, 2.29.8, and 2.30.1. 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- Restrict n8n instance access to fully trusted users only.\n- Set `N8N_SSRF_PROTECTION_ENABLED=true` to enable SSRF filtering for private IP ranges and cloud metadata endpoints.\n- Restrict network egress from the n8n host to limit reachable internal services.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","state":0,"publishedAt":"2026-07-22T22:01:10+00:00","modifiedAt":"2026-07-22T22:26:48.408353+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.123.64"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.30.0"},{"kind":"fixed","version":"2.30.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.0.0-rc.0"},{"kind":"fixed","version":"2.29.8"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:H/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-9w78-79q7-r4fp","https://nvd.nist.gov/vuln/detail/CVE-2026-65593","https://github.com/n8n-io/n8n","https://github.com/n8n-io/n8n/releases/tag/n8n@1.123.64","https://github.com/n8n-io/n8n/releases/tag/n8n@2.29.8","https://github.com/n8n-io/n8n/releases/tag/n8n@2.30.1","https://www.vulncheck.com/advisories/n8n-before-ssrf-via-dynamic-node-parameters"],"sourceUrl":"https://github.com/advisories/GHSA-9w78-79q7-r4fp","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-9w78-79q7-r4fp","identifiers":["GHSA-9w78-79q7-r4fp","CVE-2026-65593"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
