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 · moderate confidence

The Wp NssUser Register WordPress plugin (wp-nssuser-register) has an Incorrect Privilege Assignment vulnerability allowing authenticated users to escalate their privileges beyond what they should have, likely gaining administrator-level access. The plugin affects versions up to and including 1.0.0 with no patched version indicated.

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. Identify if the plugin is installed
    Check for the existence of the wp-nssuser-register directory in your WordPress wp-content/plugins/ folder. If using a file manager or command line, look for /wp-content/plugins/wp-nssuser-register/
    Affected if The plugin directory exists on the server
  2. Determine the installed version
    Open the plugin's main PHP file or readme.txt in wp-content/plugins/wp-nssuser-register/ and locate the version number in the plugin header comment
    Affected if The version is 1.0.0 or lower (since no patched version is indicated, all versions up to 1.0.0 are affected)
  3. Check if the plugin is active
    In the WordPress admin dashboard, go to Plugins > Installed Plugins and verify whether 'Wp NssUser Register' is activated. Alternatively, query the wp_options table for option_name = 'active_plugins'
    Affected if The plugin shows as active in WordPress or is listed in the active_plugins option
  4. Audit administrator-level accounts
    Navigate to Users > All Users in the WordPress admin and review all accounts with Administrator role. Check for accounts you did not create, recently created accounts, or accounts with unfamiliar email addresses/usernames
    Affected if Unexpected administrator accounts exist that were not created by known trusted administrators
  5. Review recent user role changes
    Check WordPress audit logs, security plugins, or server logs for activity around user_role metadata changes, particularly events adding Administrator role to existing users
    Affected if There are records of role escalations or administrator role assignments you did not initiate

You are affected if the wp-nssuser-register plugin is installed, active, and running version 1.0.0 or lower, especially if unauthorized administrator accounts are present.
