CVE-2026-85172: n8n

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

n8n versions before 2.34.1 contain a server-side request forgery vulnerability in the legacy request helper function exposed to Code and Function nodes. The validation logic checks the uri property for SSRF safety while the underlying HTTP client uses the url property when both are present, allowing attackers to bypass validation by supplying a safe uri alongside a malicious url to access internal addresses.

Affected products

• n8n n8n: before 2.33.4 (fixed in 2.33.4); version 2.34.0 only
