Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in n8n's dynamic node parameters endpoints. The root cause is a lack of authorization scopes in the '/rest/dynamic-node-parameters/' endpoints, combined with the ability to override a node's 'baseURL' by providing an absolute URL in the routing configuration. An authenticated attacker, regardless of their permissions to create or execute workflows, can exploit this to make the server issue HTTP requests to arbitrary internal targets. The risk is heightened because SSRF protection is disabled by default in many configurations. Patches are available in versions 1.123.64, 2.29.8, and 2.30.1.

Affected products

  • n8n-io n8n < 1.123.64, >= 2.0.0-rc.0, < 2.29.8, >= 2.30.0, < 2.30.1
