Credential exfiltration via unchecked GraphQL endpoint domain
Published Jul 22, 2026 · Updated Jul 22, 2026
Authorization bypass in the n8n GraphQL node before 1.123.64, 2.29.8, and 2.30.1 allows remote authenticated users to exfiltrate credentials. The node applies HTTP-based credentials to an attacker-controlled endpoint without enforcing each credential's Allowed HTTP Request Domains restriction. Exploitation requires workflow-editing access and a restricted credential shared with a non-owner; exposed Header, Basic, Query, or OAuth secrets reach the attacker's server.
