{"apiVersion":"1.0","identifier":"CVE-2026-77081","description":"n8n before 1.123.69, 2.x before 2.33.4, and 2.x before 2.34.1 contain an allowed-domains bypass in the GraphQL node. When the node-s Authentication parameter is set to expression mode, every authentication-gated credential selector is treated as active; if two credentials of different types are attached, the node enforces the allowed-domains policy of only the first credential while still attaching material from both. An authenticated user with workflow-authoring rights can thereby send a domain-restricted credential to an attacker-controlled endpoint, exfiltrating it with the leaked credential-s permissions.","publishedAt":"2026-08-20T12:16:39","lastModifiedAt":"2026-08-21T12:16:35","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77081","cvssScore":5.1,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:H/SI:L/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":0.00296,"riskScore":0.52,"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-2026-77081","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-77081","en":"https://www.redsauce.net/en/cves/CVE-2026-77081","fr":"https://www.redsauce.net/fr/cves/CVE-2026-77081","pt":"https://www.redsauce.net/pt/cves/CVE-2026-77081","de":"https://www.redsauce.net/de/cves/CVE-2026-77081","sk":"https://www.redsauce.net/sk/cves/CVE-2026-77081","el":"https://www.redsauce.net/el/cves/CVE-2026-77081"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-77081"}}
