When an HTTP Header Auth credential is applied to a paginated request, the secret is present in `$request.headers` when pagination expressions are evaluated. A user-controlled expression could read that secret, copy it into item data, and exfiltrate it through a later HTTP Request node, bypassing credential domain restrictions, since the secret leaves via item data rather than the credential's own request mechanism.\n\nThis issue only affects instances with `N8N_EXPRESSION_ENGINE=vm` set, where paginated HTTP Request workflows using shared credentials are accessible to non-owner users.\n\n## Patches\nThe issue has been fixed in n8n versions 1.123.61, 2.27.4, and 2.28.1. 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- Restrict workflow sharing to fully trusted users only.\n- Avoid sharing credentials with use-only access to untrusted users on workflows that use HTTP Request nodes with pagination enabled.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","state":0,"publishedAt":"2026-07-22T21:54:53+00:00","modifiedAt":"2026-07-22T22:00:25.7335783+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.123.61"}]}],"versions":[],"rawVersionEvidence":null},{"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":"2.0.0-rc.0"},{"kind":"fixed","version":"2.27.4"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/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-q3j5-8vrg-4p9q","https://nvd.nist.gov/vuln/detail/CVE-2026-59209","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-q3j5-8vrg-4p9q","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-q3j5-8vrg-4p9q","identifiers":["GHSA-q3j5-8vrg-4p9q","CVE-2026-59209"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
