CVE-2026-103093 in AI Platform
Summary
by MITRE • 10/29/2026
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.

A critical security vulnerability was identified within the ServiceNow AI Platform, specifically involving a sandbox escape mechanism that allowed for unauthorized code execution on the underlying host operating system. This flaw affected authenticated users possessing administrative privileges, enabling them to bypass the Rhino JavaScript engine's sandbox restrictions. The Rhino sandbox is designed to isolate script execution and prevent malicious or erroneous scripts from accessing sensitive data or performing destructive actions outside their designated environment. By exploiting this vulnerability, an attacker could break out of this isolated context, effectively gaining control over the server infrastructure hosting the ServiceNow instance rather than being limited to application-level interactions.
The technical nature of this flaw represents a severe breach in isolation boundaries, which is fundamental to secure multi-tenant and enterprise software architectures. When sandbox restrictions are bypassed, it transforms what might have been an account compromise into a full system compromise. This aligns with CWE identifiers such as CWE-94 Improper Control of Generation of Code (Code Injection) or CWE-200 Exposure of Sensitive Information to an Unauthorized Actor if the escape led to data leakage, but more accurately reflects CWE-78 OS Command Injection if arbitrary commands were executed directly on the host. The ability to execute arbitrary code means that an attacker could install backdoors, exfiltrate sensitive corporate data stored within the ServiceNow database, or use the compromised instance as a pivot point for lateral movement into other parts of the network infrastructure.
From an operational perspective, this vulnerability poses significant risks including unauthorized access to confidential business processes, intellectual property theft, and potential disruption of critical services managed through the platform. Although there is currently no evidence of malicious exploitation in the wild against ServiceNow instances, the severity of a sandbox escape cannot be overstated. Attackers often target such vulnerabilities because they provide high-value entry points with minimal detection if proper logging and monitoring are not in place. The lack of known active exploits provides a crucial window for organizations to harden their defenses before attackers begin leveraging this flaw at scale.
To mitigate the risk associated with this vulnerability, it is imperative that all ServiceNow customers apply the provided patches immediately. For hosted instance users, ServiceNow has already deployed these updates, but administrators should verify that their environments are running the patched version through standard update verification procedures. Self-hosted and partner-managed instances must be upgraded to a release that includes the fix for this sandbox escape issue. Additionally, organizations should review access controls to ensure that administrative privileges are granted only to trusted individuals following the principle of least privilege. Implementing robust monitoring solutions can help detect any anomalous activity resulting from potential exploitation attempts, such as unusual process executions or network connections originating from the ServiceNow server infrastructure.
