critical Nessus Plugin ID 371202

Synopsis

ServiceNow AI Platform is affected by multiple vulnerabilities.

Description

The version of the ServiceNow AI Platform (Now Platform) running on the remote host is missing the remediations described in the August 2026 CVE Advisory Notification. It is, therefore, affected by multiple vulnerabilities, including the following:

- A sandbox escape vulnerability that could allow an unauthenticated user to execute arbitrary code within the Now Platform, potentially leading to more access to the Now Platform than intended.
(CVE-2026-6876)

- A code injection vulnerability that 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. (CVE-2026-18885)

- A SQL injection vulnerability that could enable an unauthenticated user, in certain circumstances, to execute arbitrary SQL statements against the instance's underlying database and gain access to, or modify, instance data beyond what was intended. (CVE-2026-74820)

- An improper access control vulnerability that could enable an unauthenticated user, in certain circumstances, to create or modify instance data beyond what was intended, resulting in privilege escalation. (CVE-2026-18886)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
