Associated Vulnerability

Title: Sandbox Escape in ServiceNow AI Platform (CVE-2026-6875)
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.

Description

ServiceNow AI Platform (Brazil, Australia, Zurich, and Yokohama releases before patching) contains a pre-authentication remote code execution vulnerability. The /assessment_thanks.do endpoint passes the sysparm_assessable_type parameter into GlideRecord's addQuery(), which evaluates "javascript:" prefixed values as JavaScript in a restricted script sandbox. A sandbox escape gadget using Object.defineProperty and Class.create.constructor chains through the gs.include('ItemViewElementsProvider') path to invoke Function(code)(), bypassing the sandbox and executing arbitrary GlideController code. Actively exploited in the wild since July 2026.
