Which versions of emittery_styled are malicious?

Every published version of emittery_styled on npm is considered malicious. Remove the package entirely.

How do I remediate emittery_styled if I installed it?

Remove emittery_styled 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 network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is emittery_styled part of a known attack campaign?

Yes — emittery_styled is associated with the GHSA-j6hp-9w2p-jwpw campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect emittery_styled in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking emittery_styled and packages like it before any post-install script runs.
