Description
ServiceNow has remediated a code injection vulnerability that was identified in the ServiceNow AI platform. This vulnerability could enable an unauthenticated user, in certain circumstances, to execute arbitrary code in the ServiceNow platform and gain access to, or modify, instance data beyond what was 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.

AI Analysis

Impact

This vulnerability is a code injection flaw in the ServiceNow AI Platform that allows an attacker without authentication to run arbitrary code on the platform and access or alter data beyond intended limits. The weakness is a classic code injection issue, enabling execution of malicious payloads through improperly validated GraphQL Composite Data API input.

Affected Systems

The affected product is the ServiceNow AI Platform. No specific version numbers are disclosed in the advisory; the vulnerability applies to all instances of the platform that have not yet been patched.

Risk and Exploitability

The CVSS score of 10 reflects a critical impact, and the vulnerability is not currently listed in CISA KEV and no EPSS score is available. Although no malicious exploitation has been reported, the vulnerability can be triggered by an unauthenticated user targeting the GraphQL API, suggesting that attackers could achieve full remote code execution and compromise the platform if the patch is not applied.

OpenCVE Recommended Actions

  • Apply the vendor‑provided security update for the ServiceNow AI Platform immediately on all hosted and self‑hosted instances.
  • Block or restrict unauthenticated access to the GraphQL Composite Data API endpoint using firewall or API‑gateway controls until the patch is in place.
  • Continuously monitor API logs for anomalous GraphQL requests and investigate signs of injection attempts.
