Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The RingCentral Communications WordPress plugin (versions 1.5-1.6.8) contains an authentication bypass in the ringcentral_admin_login_2fa_verify() function. The improper validation allows unauthenticated attackers to bypass 2FA by submitting identical bogus codes, enabling them to log in as any existing WordPress user with administrative privileges.

MitigationUpgrade the RingCentral Communications plugin to version 1.6.9 or later. If no patched version is available, disable the plugin immediately or implement additional authentication controls such as IP whitelisting or Web Application Firewall rules to block unauthorized access attempts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check if RingCentral Communications plugin is installed
    Navigate to WordPress admin > Plugins, or inspect the /wp-content/plugins/ directory for a folder named 'ringcentral' or 'ringcentral-communications'
    Affected if The plugin is present in the WordPress installation
  2. Determine the installed plugin version
    In WordPress admin, go to Plugins > Installed Plugins and find the RingCentral Communications plugin version number, or read the main plugin PHP file header which contains the 'Version' field
    Affected if Version is 1.5, 1.6.0, 1.6.1, 1.6.2, 1.6.3, 1.6.4, 1.6.5, 1.6.6, 1.6.7, or 1.6.8 (any version from 1.5 through 1.6.8 inclusive)
  3. Verify if the 2FA feature is enabled
    Check the plugin settings in WordPress admin under RingCentral Communications settings, or inspect the database options table for ringcentral_2fa_enabled or similar configuration keys
    Affected if Two-factor authentication is actively enabled for the plugin
  4. Confirm administrative users exist
    In WordPress admin, go to Users > All Users and check for users with Administrator role
    Affected if Any administrative-level WordPress users are present in the system

If the RingCentral Communications plugin is installed at version 1.5 through 1.6.8 and 2FA is enabled, the authentication bypass vulnerability is present and exploitable.
