Why does it matter?

It allows unauthenticated attackers to change arbitrary users' passwords under certain multi-site configurations, presenting high risks to system integrity and confidentiality.

Show the technical text from the sources

The Theme My Login plugin for WordPress is vulnerable to privilege escalation via account takeover in versions up to, and including, 7.2.1. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords on multi-site setups in certain configurations.
