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 WowOptin: Next-Gen Popup Maker – Create Stunning Popups and Optins for Lead Generation plugin for WordPress is vulnerable to unauthorized arbitrary plugin installation due to a missing capability check on the 'install_and_active_plugin' function in all versions up to, and including, 1.4.24. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate arbitrary plugins.

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 WowOptin plugin for WordPress contains a broken access control vulnerability where the 'install_and_active_plugin' function lacks a capability check. This allows any authenticated user with Subscriber-level access or higher to install and activate arbitrary plugins on the WordPress site, leading to full site compromise.

MitigationUpdate the plugin to version 1.4.25 or later which includes proper capability verification. If an update is unavailable, disable the plugin or restrict user registrations as an interim measure until a patch is released.

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 WowOptin plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'WowOptin' or check the wp-content/plugins directory for wowoptin folder
    Affected if WowOptin plugin is present on the site
  2. Check installed WowOptin version
    In WordPress admin_plugins list, find WowOptin and note the version number displayed, or read the version in wowoptin/readme.txt or wowoptin/wowoptin.php header
    Affected if Version is below 1.4.25
  3. Determine if user registration is enabled
    In WordPress admin, go to Settings > General and check 'Membership - Anyone can register' setting, or inspect wp_options table for 'users_can_register' value = 1
    Affected if User registration is enabled (anyone can register as a subscriber)
  4. Check for existing Subscriber-level users
    In WordPress admin > Users, look for users with 'Subscriber' role, or query wp_users joined with wp_usermeta where meta_key = 'wp_capabilities' and meta_value contains 'subscriber'
    Affected if Any Subscriber-level user accounts exist on the site

User is affected if WowOptin plugin is installed with a version below 1.4.25 AND user registration is open OR existing Subscriber accounts are present, allowing privilege escalation via the unauthenticated plugin installation function.
