Summary

Duplicate Advisory: Authenticated SSRF via Dynamic Node Parameters Endpoints Allows Internal Network Access

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-9w78-79q7-r4fp. This link is maintained to preserve external references.

Original Description

n8n versions before 1.123.64 contain a server-side request forgery vulnerability in the dynamic-node-parameters endpoints that lack authorization scopes. Authenticated attackers can supply absolute URLs in routing configuration to override baseURL restrictions and make the n8n server issue HTTP requests to arbitrary internal targets when SSRF protection is disabled.

Severity

6.3 (Medium)
