Summary
ServiceNow has remediated an improper access control vulnerability that was identified in the ServiceNow AI platform. This vulnerability could enable an unauthenticated user, in certain circumstances, to create or modify instance data beyond what was intended, resulting in privilege escalation.
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 exploitation against ServiceNow instances.
We recommend customers promptly apply appropriate updates or upgrade to a patched release if they have not already done so.
