Because of a security vulnerability addressed in the most recent release of wp-cli, we’ve upgraded from 2.4.0 to 2.5.0. If you have installed your own copy of wp-cli under your home directory, now is a good time to upgrade! You can check where you’re getting your wp-cli like this:
[cmpalmer@login2 ~]$ which wp
/usr/local/bin/wp
And you can see what version you’ve got like this:
[cmpalmer@login2 ~]$ wp cli version
WP-CLI 2.5.0
