CVE-2026-18885

ServiceNow Discloses Three CVSS 10.0 Vulnerabilities Allowing Unauthenticated Remote Code Execution and SQL Injection

ServiceNow has released security updates addressing four vulnerabilities in its AI platform, including three rated CVSS 10.0. The flaws enable unauthenticated attackers to achieve remote code execution, privilege escalation, and arbitrary SQL execution against core ITSM systems used by large enterprises worldwide. Affected components include the GraphQL Composite Data API, system configuration image upload processor, and dynamic schema ORDER BY handling. ServiceNow states it has patched hosted instances and provided hotfixes for self-hosted customers running Xanadu, Yokohama, Zurich, and Australia branches. This follows a July disclosure of a related sandbox escape tracked as CVE-2026-6875 that showed signs of in-the-wild exploitation. No public exploits or confirmed active attacks have been observed for the new issues yet, but the extremely low attack complexity leaves a narrow remediation window for organizations running exposed instances.

ServiceNow has released updated versions to address the flaws.
