When running npm audit fix to fix the send < 0.19.0 vulnerability, I get a message saying the fix can't be done because it will install a (very) old version of webpack-dev-server, which is a breaking change.

The latest version of webpack-dev-server is 5.1.0, and my product is on 4.15.2. To fix the send vulnerability, webpack-dev-server version 1.2.9 would be installed.

4 moderate severity vulnerabilities

To address all issues (including breaking changes), run:
npm audit fix --force

Forcing a fix installs the old version of webpack-dev-server, and creates 18 vulnerabilities, 4 of which are critical, and 12 high:

18 vulnerabilities (2 moderate, 12 high, 4 critical)

Maybe I'm missing a step?
