CyberRota Analysis

AI-Generated

Versions of n8n prior to 2.39.6 and between 2.40.0 and 2.40.1 are vulnerable due to inadequate validation of credential ownership during inline agent node-tool introspection. This flaw allows attackers to access arbitrary credential IDs, enabling them to decrypt and exfiltrate sensitive plaintext secrets to their own servers. Organizations using affected n8n versions should prioritize patching to mitigate the risk of credential theft and potential data breaches.

Original NVD Description

n8n versions before 2.39.6 and 2.40.0 before 2.40.1 fail to validate credential ownership during inline agent node-tool introspection. Attackers can reference arbitrary credential IDs to decrypt and exfiltrate plaintext secrets to attacker-controlled hosts without ownership verification.
