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

Missing authorization vulnerability in the Wp Ultimate Review WordPress plugin allows attackers to exploit incorrectly configured access control security levels. The plugin fails to properly verify user permissions before allowing access to certain functionalities, potentially enabling unauthorized users to access or modify review data they should not have permission to access.

MitigationUpdate the Wp Ultimate Review plugin to the latest patched version. If no update is available, implement proper access control validation at the application level or disable the plugin until a fix 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. Confirm plugin installation and activation
    Log into WordPress admin panel and navigate to Plugins > Installed Plugins. Locate 'WP Ultimate Review' in the list and verify its status is 'Active'.
    Affected if The plugin is installed and active, and its version falls at or below 2.3.8
  2. Identify installed plugin version
    In the WordPress admin Plugins page, click on the plugin name 'WP Ultimate Review' to view its details, or inspect the plugin header in /wp-content/plugins/wp-ultimate-review/ folder to read the Version field.
    Affected if The version number shown is 2.3.8 or lower
  3. Verify access control configuration
    As an administrator, navigate to the plugin settings (usually under Reviews or a dedicated WP Ultimate Review menu). Look for any access control, capability, or user role settings that define who can manage reviews.
    Affected if Settings allow low-privilege users (such as Subscribers or Contributors) or unauthenticated users to access review management features
  4. Test unauthenticated access to review endpoints
    Using a browser or HTTP tool (like curl), attempt to access common plugin AJAX endpoints or admin pages without logging in. Common paths include /wp-admin/admin-ajax.php?action=... or direct access to plugin PHP files.
    Affected if Requests return successful responses or data rather than redirecting to login or returning a permission error
  5. Inspect plugin code for capability checks
    If you have file access, examine the main plugin PHP file (wp-ultimate-review.php or similar in /wp-content/plugins/wp-ultimate-review/). Search for function calls that handle review creation, editing, deletion, or approval. Look for current_user_can() or similar authorization checks before sensitive operations.
    Affected if Sensitive review management functions lack proper current_user_can() or capability validation checks

You are affected if the WP Ultimate Review plugin is installed with a version of 2.3.8 or lower and the plugin allows unauthenticated or low-privilege users to access review management functionality without proper permission checks.
