Vulnerability Description
ServiceNow has addressed a remote code execution vulnerability that was identified in the ServiceNow AI platform. This vulnerability could enable an unauthenticated user, in certain circumstances, to execute code within the ServiceNow platform.
ServiceNow addressed this vulnerability by deploying a security update to hosted instances. Relevant security updates have also been provided to ServiceNow self-hosted customers and partners.
Further, the vulnerability is addressed in the listed patches and family releases, which have been made available to hosted and self-hosted customers, as well as partners. 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.
Recommended Actions
Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (380026 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.
Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.
- Affected versions: ServiceNow ServiceNow AI Platform versions earlier than Australia Patch 2.
- Affected versions: ServiceNow ServiceNow AI Platform versions earlier than Yokohama Patch 12 Hot Fix 1b.
- Affected versions: ServiceNow ServiceNow AI Platform versions earlier than Yokohama Patch 13.
- Affected versions: ServiceNow ServiceNow AI Platform versions earlier than Zurich Patch 7b.
- Affected versions: ServiceNow ServiceNow AI Platform versions earlier than Zurich Patch 9.
- Affected versions: ServiceNow ServiceNow AI Platform versions earlier than Brazil EA.
- Affected versions: ServiceNow ServiceNow AI Platform versions earlier than Brazil GA.
- No specific CNA/vendor solution or workaround is included in the current CVE Record (opens in a new tab) . Review the vendor’s security advisories and supported-release guidance before making changes.
Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.
Research Notes
Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context
This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.
Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
