## Overview

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.

## Affected

- `n8n >= 2.32.0 < 2.32.1`
- `n8n < 2.31.5`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
