ServiceNow has addressed a domain separation bypass security issue that was identified in the ServiceNow SR – CSM – Task Plan Templates Store application. This vulnerability could enable an authenticated user with a specific role to create records in domains they do not have access to, potentially leading to unauthorized data creation across domain boundaries. We are not currently aware of malicious exploitation against ServiceNow instances. We recommend customers promptly apply appropriate updates or upgrade to a patched release if they have not already done so.
