CVE-2026-65596 PUBLISHED

n8n before 1.123.64 Credential Exfiltration via GraphQL Node

Assigner: VulnCheck
Reserved: 22.07.2026 Published: 22.07.2026 Updated: 22.07.2026

n8n before 1.123.64, 2.29.8, and 2.30.1 fails to enforce the "Allowed HTTP Request Domains" restriction on HTTP-based credentials (Header Auth, Basic Auth, Query Auth, OAuth) in the GraphQL node, unlike the HTTP Request node. An authenticated user able to create or edit workflows can point the node's endpoint at a server they control and exfiltrate restricted credentials. Only instances where a credential has "Allowed HTTP Request Domains" configured and is usable by non-owner users are affected.
