What is CVE-2026-65593?

n8n versions prior to 1.123.64 are susceptible to a server-side request forgery vulnerability located in the dynamic-node-parameters endpoints. This issue arises due to inadequate authorization scopes, allowing authenticated users to submit absolute URLs in routing configurations. When SSRF protection is disabled, this manipulation can enable attackers to circumvent baseURL restrictions and direct the n8n server to execute HTTP requests to arbitrary internal resources, posing significant security risks.

Affected Version(s)

n8n 0 < 1.123.64

n8n 0 < 2.30.1

n8n 0 < 2.29.8
