{"apiVersion":"1.0","identifier":"CVE-2026-77076","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":"2026-08-20T12:16:38","lastModifiedAt":"2026-08-21T17:16:46","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77076","cvssScore":7.1,"cvssVector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00287,"riskScore":0.73,"affectedProduct":"n8n","affectedVersions":"<1.123.69, <2.33.4, <2.34.1","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-77076","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-77076","en":"https://www.redsauce.net/en/cves/CVE-2026-77076","fr":"https://www.redsauce.net/fr/cves/CVE-2026-77076","pt":"https://www.redsauce.net/pt/cves/CVE-2026-77076","de":"https://www.redsauce.net/de/cves/CVE-2026-77076","sk":"https://www.redsauce.net/sk/cves/CVE-2026-77076","el":"https://www.redsauce.net/el/cves/CVE-2026-77076"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-77076"}}
