How do I remediate security-util-py if I installed it?

Remove security-util-py 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 security-util-py — how do I know if it already compromised me?

If security-util-py 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.
