CVE-2026-72771
n8n before 2.32.1 Credential Restriction Bypass via AI/LLM Nodes
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.

n8n: Bypass "Allowed HTTP Request Domains" Credential Restriction in Multiple AI and LLM Nodes
Impact
The credential "Allowed HTTP Request Domains" allowlist was intended to restrict which hosts a credential's secret could be sent to, protecting shared credentials from users who could use but not view them. Several AI/LLM nodes did not enforce this allowlist when a user-supplied base or endpoint URL was set. A low-privileged workflow editor with use-only access to such a shared credential could point one of these nodes at an attacker-controlled host and cause the credential secret to be transmitted there, then reuse it against the underlying service.
Only instances where a credential has "Allowed HTTP Request Domains" configured and is shared with non-owner users are affected.
Patches
The issue has been fixed in n8n versions 2.31.5 and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability.
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
- Restrict workflow creation and editing permissions to fully trusted users only.
- Restrict credential sharing to fully trusted users only.
- Audit credentials with domain restrictions for unexpected sharing relationships.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
