Server-Side Request Forgery in n8n Prior to 1.123.64

Publication date: 2026-07-22

Last updated on: 2026-07-22

Assigner: VulnCheck

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.

Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in n8n versions before 1.123.64. Authenticated attackers can exploit endpoints in /rest/dynamic-node-parameters/ to bypass authorization scopes and make the n8n server issue HTTP requests to arbitrary internal network targets by providing absolute URLs in routing configuration.

Detection Guidance

To detect this vulnerability, check if your n8n instance is running a vulnerable version (before 1.123.64, 2.29.8, or 2.30.1). Inspect network traffic for unexpected outbound HTTP requests from the n8n server, especially to internal network targets. Review logs for access to /rest/dynamic-node-parameters/ endpoints by unauthorized users.

Impact Analysis

An attacker could use this to access internal systems, exfiltrate data, or perform unauthorized actions on behalf of the n8n server. This is especially risky if SSRF protection is disabled, allowing requests to internal targets.

Mitigation Strategies

Upgrade n8n to a patched version (1.123.64, 2.29.8, or 2.30.1) immediately. Enable SSRF protection by setting N8N_SSRF_PROTECTION_ENABLED=true. Restrict access to the n8n instance to trusted users only. Limit network egress from the n8n host to prevent unauthorized outbound requests.
