Summary

The Social Login & Sharing buttons with Analytics By SoClever WordPress plugin through 1.2.0 does not perform any authentication, authorisation or nonce checks in one of its publicly accessible login handlers, allowing unauthenticated attackers to obtain a valid session as any existing user, including administrators. In the default case a session as the site's original administrator account is obtained without needing to know any account details at all.
