// Underscore.js 1.3.3

The package underscore from 1.13.0-0 and before 1.13.0-2, from 1.3.2 and before 1.12.1 are vulnerable to Arbitrary Code Injection via the template function, particularly when a variable property is passed as an argument as it is not sanitized.

srouce: https://nvd.nist.gov/vuln/detail/CVE-2021-23358

p.s
I did quick tests and it appears that replacing it with Underscore.js 1.13.6 doesn't seem to cause any damage.
