ServiceNow customers and administrators responsible for Utah, Vancouver, or Washington DC Now Platform deployments should treat this as urgent, especially if the platform is Internet-accessible or supports sensitive business workflows.

Technical summary

The published record identifies the flaw as an incomplete list of disallowed inputs vulnerability in the ServiceNow Now Platform.

Defensive priority

Critical. The KEV designation and remediation due date indicate this should be addressed immediately, using vendor guidance or compensating controls if patching is not immediately possible.

Recommended defensive actions

• Review the ServiceNow security guidance referenced by CISA, including the vendor KB article cited in the source notes (KB1648313).
• Apply vendor-recommended mitigations or updates as soon as they are available for the affected Now Platform releases.
