Description

ServiceNow has remediated a sandbox escape security issue that was identified in the ServiceNow AI Platform. This vulnerability could enable an authenticated user with the admin role to bypass Rhino sandbox restrictions and execute arbitrary code on the underlying host operating system, potentially enabling further unintended access. ServiceNow deployed an 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.
