Which versions of font_fabulous are malicious?

The following RubyGems versions of font_fabulous are flagged malicious: 1.0.5. Treat any of these as compromised.

How do I remediate font_fabulous if I installed it?

Remove font_fabulous 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_fabulous — how do I know if it already compromised me?

If font_fabulous was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
