Which versions of csec-form-helpers are malicious?

The following npm versions of csec-form-helpers are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate csec-form-helpers if I installed it?

Remove csec-form-helpers 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 csec-form-helpers — how do I know if it already compromised me?

If csec-form-helpers 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 — csec-form-helpers is associated with the RLMA-2026-05037, RLUA-2026-06172 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 csec-form-helpers across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for csec-form-helpers (version 1.0.0).
