Which versions of font_awesome-sass are malicious?

The following RubyGems versions of font_awesome-sass are flagged malicious: 5.12.0. Treat any of these as compromised.

How do I remediate font_awesome-sass if I installed it?

Remove font_awesome-sass from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed font_awesome-sass — how do I know if it already compromised me?
