Which versions of jsonauthcap are malicious?

The following npm versions of jsonauthcap are flagged malicious: 7.2.7. Treat any of these as compromised.

How do I remediate jsonauthcap if I installed it?

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

If jsonauthcap 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.

Is jsonauthcap part of a known attack campaign?

Yes — jsonauthcap is associated with the RLMA-2025-06376, RLUA-2026-01373 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 jsonauthcap across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for jsonauthcap (version 7.2.7).
