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 BeyondCart Connector plugin for WordPress is vulnerable to Privilege Escalation due to improper JWT secret management and authorization within the determine_current_user filter in versions 1.4.2 through 3.0.1. This makes it possible for unauthenticated attackers to craft valid tokens and assume any user’s identity.

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 BeyondCart Connector WordPress plugin (versions 1.4.2-3.0.1) contains a critical privilege escalation vulnerability stemming from improper JWT secret management and a flaw in the determine_current_user filter. Attackers can forge valid JWT tokens without knowing the secret, allowing them to authenticate as any user on the WordPress site, including administrators.

MitigationUpdate the BeyondCart Connector plugin to the latest version once a patch is released. Additionally, audit existing user accounts for unauthorized administrative accounts and rotate any exposed credentials.

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. Verify BeyondCart Connector plugin version
    Navigate to WordPress admin dashboard > Plugins > Installed Plugins. Locate 'BeyondCart Connector' and read the version number from the plugin description. Alternatively, check the plugin header in /wp-content/plugins/beyondcart-connector/beyondcart-connector.php for the 'Version' comment.
    Affected if The installed version falls within 1.4.2 through 3.0.1 inclusive.
  2. Confirm plugin is active
    In the WordPress Plugins admin page, verify that BeyondCart Connector shows as 'Active' rather than 'Inactive' or 'Must Use'.
    Affected if The plugin is active and the version is in the affected range.
  3. Inspect WordPress user accounts for unauthorized admins
    Navigate to WordPress admin > Users. Review the list for any admin accounts you did not create, especially those with generic usernames or created recently. Check user registration dates and last login times.
    Affected if There are admin accounts you did not create, or existing admin accounts with unexpected last-login dates.
  4. Review authentication logs for anomalous JWT activity
    Check WordPress debug logs (wp-content/debug.log if logging is enabled) and server access logs for POST requests to /wp-json/beyondcart/v1/auth or similar endpoints. Look for successful authentications from IP addresses you do not recognize.
    Affected if There are authenticated requests from unknown sources or unusual authentication patterns.
  5. Check for the JWT authentication endpoint exposure
    Make a test GET request to /wp-json/beyondcart/v1/auth or /wp-json/beyondcart/auth/validate using curl or a browser. If the endpoint responds (even with an error), the plugin's authentication handler is active.
    Affected if The endpoint responds and the plugin version is in the affected range.

You are affected if the BeyondCart Connector plugin is installed, active, and version 1.4.2-3.0.1, or if unauthorized admin accounts exist in your WordPress users table.
