{"id":"CVE-2026-77076","state":"PUBLISHED","title":"n8n before 1.123.69 Credential Leak via GraphQL Node Error","description":"n8n versions before 1.123.69, 2.33.4, and 2.34.1 contain an information disclosure vulnerability in the GraphQL node. When a GraphQL request fails at the connection level, the node re-throws the underlying HTTP client error unchanged instead of wrapping it in n8n's standard error type. That error contains the live request's headers, including a decrypted credential secret, which the execution engine persists verbatim. Any authenticated user able to read the resulting execution can retrieve the decrypted credential secret from the stored run data.","publishedAt":"2026-08-20T11:21:10.251Z","updatedAt":"2026-08-21T16:43:12.650Z","severity":{"score":7.1,"label":"High","version":"4.0","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","source":"VulnCheck"},"assigner":"VulnCheck","products":["n8n-io n8n"],"affected":[{"vendor":"n8n-io","product":"n8n","packageURL":"pkg:npm/n8n","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"1.123.69","versionType":"semver"},{"version":"1.123.69","status":"unaffected","versionType":"semver"}]},{"vendor":"n8n-io","product":"n8n","packageURL":"pkg:npm/n8n","defaultStatus":"unaffected","versions":[{"version":"2.34.0","status":"affected","lessThan":"2.34.1","versionType":"semver"},{"version":"2.34.1","status":"unaffected","versionType":"semver"}]},{"vendor":"n8n-io","product":"n8n","packageURL":"pkg:npm/n8n","defaultStatus":"unaffected","versions":[{"version":"2.0.0","status":"affected","lessThan":"2.33.4","versionType":"semver"},{"version":"2.33.4","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-9fqj-7wc5-cwhx","https://www.vulncheck.com/advisories/n8n-before-credential-leak-via-graphql-node-error"],"weaknesses":["CWE-209"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/77xxx/CVE-2026-77076.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-77076","state":"PUBLISHED","datePublished":"2026-08-20T11:21:10.251Z","dateUpdated":"2026-08-21T16:43:12.650Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-08-20T10:51:39.784Z"},"containers":{"cna":{"title":"n8n before 1.123.69 Credential Leak via GraphQL Node Error","descriptions":[{"lang":"en","value":"n8n versions before 1.123.69, 2.33.4, and 2.34.1 contain an information disclosure vulnerability in the GraphQL node.
