Description
n8n is an open source workflow automation platform. Prior to 1.121.0, there is a vulnerability in the HTTP Request node's credential domain validation allowed an authenticated attacker to send requests with credentials to unintended domains, potentially leading to credential exfiltration. This only might affect user who have credentials that use wildcard domain patterns (e.g., *.example.com) in the "Allowed domains" setting. This issue is fixed in version 1.121.0 and later.
Analysis
Improper credential domain validation in n8n's HTTP Request node prior to version 1.121.0 enables authenticated attackers to redirect requests containing credentials to unintended domains, risking credential theft for users with wildcard domain patterns in their allowed domains configuration. The vulnerability requires valid authentication and has a low exploitation probability, with no public exploit currently available.
