ServiceNow AI Platform - Pre-Auth JavaScript Sandbox Escape RCE

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.

A XSS vulnerability was identified in the ServiceNow UI page assessment_redirect. To exploit this vulnerability, an attacker would need to persuade an authenticated user to click a maliciously crafted URL. Successful exploitation potentially could be used to conduct various client-side attacks, including, but not limited to, phishing, redirection, theft of CSRF tokens, and use of an authenticated user's browser or session to attack other systems.
