Which versions of xwandpdf1 are malicious?

The following RubyGems versions of xwandpdf1 are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate xwandpdf1 if I installed it?

Remove xwandpdf1 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 xwandpdf1 — how do I know if it already compromised me?

If xwandpdf1 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 xwandpdf1 part of a known attack campaign?

Yes — xwandpdf1 is associated with the RLMA-2026-04195, RLUA-2026-10128 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 xwandpdf1 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for xwandpdf1 (version 0.0.1).
