Last modified
CVE-2026-72771 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
