  "details": "## Impact\n\nThe credential \"Allowed HTTP Request Domains\" allowlist was intended to restrict which hosts a credential\u0027s 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.\n\nOnly instances where a credential has \"Allowed HTTP Request Domains\" configured and is shared with non-owner users are affected.\n\n## Patches\nThe 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.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict workflow creation and editing permissions to fully trusted users only.\n- Restrict credential sharing to fully trusted users only.\n- Audit credentials with domain restrictions for unexpected sharing relationships.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.",
