Official description

The WooCommerce - Social Login plugin for WordPress is vulnerable to unauthenticated privilege escalation in all versions up to, and including, 2.7.3. This is due to a lack of brute force controls on a weak one-time password. This makes it possible for unauthenticated attackers to brute force the one-time password for any user, except an Administrator, if they know the email of user.

The underlying weakness: Authentication Bypass by Primary Weakness

The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.
