## 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.
