CVE-2026-65593: n8n

Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

n8n versions before 1.123.64, 2.29.8, and 2.30.1 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.

Affected products

• n8n n8n: before 1.123.64 (fixed in 1.123.64); from 2.0.0, before 2.29.8 (fixed in 2.29.8); version 2.30.0 only
