Which versions of rate-limits-flexible are malicious?

Every published version of rate-limits-flexible on npm is considered malicious. Remove the package entirely.

How do I remediate rate-limits-flexible if I installed it?

Remove rate-limits-flexible 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 rate-limits-flexible part of a known attack campaign?

Yes — rate-limits-flexible is associated with the GHSA-hg8j-2wmv-w4v6 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 rate-limits-flexible 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 rate-limits-flexible and packages like it before any post-install script runs.
