n8n: SecurityScorecard Node Leaks API Token to User-Controlled Host
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.
