Which versions of matplotlib-requests are malicious?

The following PyPI versions of matplotlib-requests are flagged malicious: 16.12.4. Treat any of these as compromised.

How do I remediate matplotlib-requests if I installed it?

Remove matplotlib-requests 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 matplotlib-requests — how do I know if it already compromised me?

If matplotlib-requests 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.

How do I find matplotlib-requests across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for matplotlib-requests (version 16.12.4).
