Which versions of req-matplotlib are malicious?

The following PyPI versions of req-matplotlib are flagged malicious: 11.2.18. Treat any of these as compromised.

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

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

If req-matplotlib 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.
