Summary
In n8n before versions 1.123.55, 2.25.7, and 2.26.1, an authenticated user with permission to create or modify workflows and access to a SecurityScorecard credential with limited allowed domains could configure the SecurityScorecard node's report download operation to target an attacker-controlled URL. The node attached the SecurityScorecard API token to the outbound request, causing the credential to be sent to the attacker-controlled host bypassing credential configured limitations and exfiltrating.
Risk Assessment
The risk involves the exfiltration of a sensitive SecurityScorecard API token to an external attacker, potentially enabling unauthorized access to data and resources protected by that credential, bypassing configured domain restrictions.
Recommendation
Immediately update n8n to version 1.123.55, 2.25.7, or 2.26.1, depending on the branch in use. After updating, also verify and potentially rotate any SecurityScorecard API tokens that may have been compromised.
Original NVD description (English source)
n8n is an open source workflow automation platform. Prior to 1.123.55, 2.25.7, and 2.26.1, an authenticated user with permission to create or modify workflows and access to a SecurityScorecard credential with limited allowed domains could configure the SecurityScorecard node's report download operation to target an attacker-controlled URL. The node attached the SecurityScorecard API token to the outbound request, causing the credential to be sent to the attacker-controlled host bypassing credential configured limitations and exfiltrating. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.1.
