CVE-2026-72771

MediumCVSS 6.5/10Last modified Oct 29, 2026

Description

n8n versions before 2.32.1 fail to enforce the Allowed HTTP Request Domains allowlist in multiple AI and LLM nodes when user-supplied base or endpoint URLs are configured. Low-privileged workflow editors with use-only access to shared credentials can redirect requests to attacker-controlled hosts and exfiltrate credential secrets for reuse against underlying services.
