CyberRota Analysis

AI-Generated

The vulnerability affects n8n versions prior to 1.123.69 and 2.x before 2.33.4 and 2.34.1, allowing an authenticated user with workflow-authoring rights to bypass the allowed-domains policy in the GraphQL node. This flaw enables the exfiltration of domain-restricted credentials to attacker-controlled endpoints, potentially compromising sensitive data and permissions. Organizations using affected versions should prioritize patching to mitigate the risk of credential leakage.

Original NVD 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.
