We got a dependable alert for the dependency referencing this issue medikoo/es5-ext#201 on which there is a direct version dependency

dev-tunnels/ts/src/connections/package.json

Line 28 in 038b9f8

"es5-ext": "0.10.63"

Also, unless you need to support IE 11 or Node 0.12 (end of life since 2014) you probably don't need that dependency https://compat-table.github.io/compat-table/es6/
