NVD · CVE.org

n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could achieve global prototype pollution via an unvalidated pagination parameter in the HTTP Request node. Combined with other techniques this could lead to RCE on the instance. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7.
