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
Editor Remote Code Execution (RCE) in Responsive Slider by MetaSlider <= 3.106.0 versions.

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

A Remote Code Execution (RCE) vulnerability exists in the Responsive Slider by MetaSlider WordPress plugin's editor functionality, affecting all versions up to and including 3.106.0. This critical flaw allows authenticated attackers (or potentially unauthenticated depending on configuration) to execute arbitrary code on the server through the plugin's editor component.

MitigationUpdate the Responsive Slider by MetaSlider plugin to the latest patched version immediately. If no patched version is available, consider removing the plugin until a fix is released, or implement additional access controls on the /wp-admin/ area as a temporary measure.

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 Responsive Slider by MetaSlider is installed
    Log in to the WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'Responsive Slider by MetaSlider' in the list of active plugins.
    Affected if The plugin is installed and active in WordPress.
  2. Determine the installed plugin version
    In the Plugins list, locate the Responsive Slider by MetaSlider entry. The version number is displayed beneath the plugin name. Alternatively, check the plugin's main PHP file header for the 'Version' comment, typically found in the plugin's root directory (e.g., /wp-content/plugins/ml-slider/).
    Affected if The installed version is 3.106.0 or any earlier version.
  3. Verify if the editor functionality is accessible
    Navigate to the plugin's editor interface in the WordPress admin (typically under MetaSlider or Slides in the left sidebar). Attempt to access the slide editor or slider creation interface.
    Affected if The editor interface loads and accepts input without additional authentication beyond standard WordPress admin access.
  4. Check wp-admin access controls
    Review your WordPress site's access configuration. Inspect whether the /wp-admin/ directory and wp-login.php are restricted to specific IP addresses, require strong authentication, or are publicly accessible. Check .htaccess, security plugins, or server configuration.
    Affected if The wp-admin area is publicly accessible without IP restrictions or additional authentication layers.

A user is affected if the Responsive Slider by MetaSlider plugin version 3.106.0 or lower is installed and active, with the editor functionality accessible to authenticated users or exposed without proper access controls.
