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 Hostinger Reach – AI-Powered Email Marketing for WordPress plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'handle_ajax_action' function in all versions up to, and including, 1.3.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to use the 'hostinger_reach_connection_notice_action' action to update the API key value stored in the database. This vulnerability can only be exploited when the plugin is not connected to a site and no API key value exists in the database.

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 Hostinger Reach WordPress plugin lacks proper capability validation in its AJAX handler function 'handle_ajax_action'. The vulnerable 'hostinger_reach_connection_notice_action' action allows any authenticated user with Subscriber-level access to update the API key value in the database when the plugin is not yet connected.

MitigationUpdate to version 1.3.9 or later which implements proper capability checks on the affected AJAX action. Until then, ensure no untrusted users have Subscriber-level WordPress accounts on sites using this plugin.

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 Hostinger Reach plugin is installed
    Check your WordPress plugins directory or the Plugins page in wp-admin for 'Hostinger Reach'
    Affected if Plugin is present in the WordPress installation
  2. Check the installed plugin version
    Navigate to Plugins > Installed Plugins > Hostinger Reach and view the version number displayed
    Affected if Version is below 1.3.9 (or version cannot be determined)
  3. Determine if the plugin is unconnected
    Check the plugin settings or database for the presence/value of the API key configuration. In WordPress admin, visit the Hostinger Reach settings page and verify if it shows as 'Not connected' or requires initial setup.
    Affected if Plugin has not been connected yet (no API key configured)
  4. Identify Subscriber-level user accounts
    In WordPress admin, go to Users > All Users and review the role column for accounts with 'Subscriber' role. Alternatively, query wp_users and wp_usermeta for user_login and meta_key='wp_capabilities' containing 'subscriber'.
    Affected if There are any user accounts with Subscriber role on the site

You are affected if Hostinger Reach plugin below version 1.3.9 is installed, has not yet been connected (no API key set), AND there exists at least one Subscriber-level user account on the site.
