Social Share, Social Login and Social Comments <= 7.10.6 - Authentication Bypass

  • Disclosed: 03.03.2018
  • Updated: 11.10.2026 10:23

The Social Share, Social Login and Social Comments plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the 'the_champ_user_auth' AJAX action in versions up to, and including, 7.10.6. This makes it possible for unauthenticated attackers to log in as any user, assuming they know their email address.
