Dear VulDB Team,
I would like to request an update regarding the CPE assignment for CVE‑2025‑12420.
No specific CPE entry appears in the NVD/NIST record, and since ServiceNow Store Apps do not have dedicated CPE identifiers, the generic and widely used `cpe:2.3:a:servicenow:servicenow` may be appropriate for this case.
Could you please consider adding this CPE to the corresponding vulnerability entry?
Thank you for your support.
