Technical description
The RingCentral Communications plugin for WordPress is vulnerable to Authentication Bypass due to improper validation within the ringcentral_admin_login_2fa_verify() function in versions 1.5 to 1.6.8. This makes it possible for unauthenticated attackers to log in as any user simply by supplying identical bogus codes.
