transitive dependency @tootallnate/once has an advisory and is flaged as a low vulnerability

Unable to update dependency on vulnerable npm package. I tried doing this with dependabot in my project:

Dependabot cannot update @tootallnate/once to a non-vulnerable version The latest possible version that can be installed is 2.0.0 because of the following conflicting dependencies:
firebase-functions-test@3.4.1 requires @tootallnate/once@2 via a transitive dependency on http-proxy-agent@5.0.0
firebase-functions@7.0.5 requires @tootallnate/once@2 via a transitive dependency on http-proxy-agent@5.0.0
firebase-admin@13.6.1 requires @tootallnate/once@2 via a transitive dependency on http-proxy-agent@5.0.0
No patched version available for @tootallnate/once The earliest fixed version is 3.0.1.
