Is xzvbailss safe?

Version 1.0.0 of xzvbailss was compromised (WhatsApp channel hijack (PhantomSub): follows publisher-chosen channels through the user's session). Other versions are not flagged as malicious. npm's latest tag points to 1.0.0, one of these versions, so an unpinned install gets it.

Do not install xzvbailss 1.0.0

If one of these versions was installed, remove it and treat the credentials, tokens and SSH keys on that machine as exposed: rotate them. Check CI runners and container images that installed it too.
