12 vulnerabilities (2 low, 5 moderate, 5 high)

I believe these are the relevant warnings:

npm WARN deprecated cryptiles@2.0.5: This version has been deprecated in accordance with the hapi support policy (hapi.im/support). Please upgrade to the latest version to get the best features, bug fixes, and security patches.

npm WARN deprecated hawk@3.1.3: This module moved to @hapi/hawk. Please make sure to switch over as this distribution is no longer supported and may contain bugs and critical security issues.

The fix is probably just upgrading the versions in package.json.
