Dependencies using vulnerable postcss version

[jeroentvb]

spicetify-creator is using typescript-plugin-css-modules, which has dependencies using on a vulnerable version of postcss. For example postcss-filter-plugins depends on version 6 of postcss, while the current is version 8.

There is an open issue on typescript-plugin-css-modules about this issue located here. But doesn't look like anything is being done about it.
The issue has been created the 7th of january this year, while the last release was the 5th of june 2021.

Is there anything to be done to resolve this, or do we wait for the dependencies to update (which will take a while, or may not happen at all).
