[trisberg]

Dependabot cannot update webpack-dev-middleware to a non-vulnerable version
The latest possible version that can be installed is 5.3.3 because of the following conflicting dependencies:

@angular-devkit/[email protected] requires [email protected]
No patched version available for webpack-dev-middleware

The earliest fixed version is 5.3.4.

Dependabot cannot update follow-redirects to a non-vulnerable version
The latest possible version that can be installed is 1.15.4 because of the following conflicting dependencies:

@angular-devkit/[email protected] requires [email protected] via a transitive dependency on [email protected]
[email protected] requires [email protected] via [email protected]
[email protected] requires [email protected] via a transitive dependency on [email protected]
[email protected] requires [email protected] via a transitive dependency on [email protected]
