Endpoints in /rest/dynamic-node-parameters/ lacked authorization scopes, making it reachable by any authenticated user with no workflow creation or execution required.
By supplying an absolute URL in the routing configuration, a caller could override the node type's declared baseURL, defeating the restriction meant to confine requests to the node's own upstream service. With SSRF protection disabled by default (N8N_SSRF_PROTECTION_ENABLED=false), this let an authenticated user make the n8n server issue HTTP requests to arbitrary internal targets.
The issue has been fixed in n8n versions 1.123.64, 2.29.8, and 2.30.1. Users should upgrade to this version or later to remediate the vulnerability.
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
N8N_SSRF_PROTECTION_ENABLED=true to enable SSRF filtering for private IP ranges and cloud metadata endpoints.These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
