CVE-2025-11438Public exploitNetwork attack vector

Member-level custom-domain modification via missing policy check

Published Oct 8, 2025 · Updated Oct 8, 2025

Missing authorization in OpnForm 1.9.0 through 1.9.3 allows remote authenticated users to alter workspace custom domains. WorkspaceController::saveCustomDomain accepts the requested workspace and updates its custom domains without invoking the adminAction policy. A non-admin member account and a Pro workspace are required; successful exploitation changes that workspace's custom-domain configuration.
