## Description

The LatePoint plugin for WordPress is vulnerable to a login rate limit bypass in versions 5.2.10 up to, and including, 5.7.6, due to the per-contact attempt counter being keyed on the raw submitted email or phone value while the account lookup is not case-sensitive, and the per-IP counter trusting client-supplied IP headers. This makes it possible for unauthenticated attackers to make unlimited password guesses against a customer account.
