{"id":"GHSA-rm2v-h48j-895m","summary":"n8n: SecurityScorecard Node Leaks API Token to User-Controlled Host","details":"## Impact\nAn authenticated user with permission to create or modify workflows and access to a SecurityScorecard credential with limited allowed domains could configure the SecurityScorecard node's report download operation to target an attacker-controlled URL. The node attached the SecurityScorecard API token to the outbound request, causing the credential to be sent to the attacker-controlled host bypassing credential configured limitations and exfiltrating.\n\n## Patches\nThe issue has been fixed in n8n versions 1.123.55, 2.25.7, and 2.26.1. 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 SecurityScorecard node by adding `n8n-nodes-base.securityScorecard` 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.","aliases":["CVE-2026-54304"],"modified":"2026-07-20T14:00:25.542030296Z","published":"2026-06-16T23:34:10Z","database_specific":{"cwe_ids":["CWE-200"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-06-16T23:34:10Z","nvd_published_at":"2026-06-23T17:17:06Z"},"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-rm2v-h48j-895m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54304"},{"type":"PACKAGE","url":"https://github.com/n8n-io/n8n"}],"affected":[{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.123.55"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-rm2v-h48j-895m/GHSA-rm2v-h48j-895m.json"}},{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.26.0"},{"fixed":"2.26.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-rm2v-h48j-895m/GHSA-rm2v-h48j-895m.json"}},{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0-rc.0"},{"fixed":"2.25.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-rm2v-h48j-895m/GHSA-rm2v-h48j-895m.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:L/SA:N"}]}
