Title
Sandbox Escape in Now Platform
Summary
ServiceNow has remediated a sandbox escape security issue that was identified in the Now Platform. This security issue could allow an unauthenticated user to execute arbitrary code within the Now Platform, potentially leading to more access to the Now Platform than intended.
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.
