Which versions of bootstrap-setcolors are malicious?

The following npm versions of bootstrap-setcolors are flagged malicious: 1.9.16. Treat any of these as compromised.

How do I remediate bootstrap-setcolors if I installed it?

Remove bootstrap-setcolors 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 bootstrap-setcolors — how do I know if it already compromised me?

If bootstrap-setcolors 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.

Yes — bootstrap-setcolors is associated with the RLMA-2025-06072, RLUA-2026-01130 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find bootstrap-setcolors across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for bootstrap-setcolors (version 1.9.16).
