Description

ServiceNow has remediated an improper access control security issue that was identified in the ServiceNow AI Platform. This security issue could enable an unauthenticated user, in certain circumstances, to create, modify, or delete instance data beyond what was intended. In August 2026, ServiceNow deployed a security update to hosted instances and ServiceNow provided the update to our partners and self-hosted customers. 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.
