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 Appsero Helper plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.2. This is due to missing or incorrect nonce validation on the 'appsero_helper' page. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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 Appsero Helper WordPress plugin versions up to 1.3.2 lack proper nonce validation on the appsero_helper admin page, allowing unauthenticated attackers to forge administrative requests. This CSRF vulnerability enables attackers to modify plugin settings and inject malicious scripts by tricking administrators into clicking crafted links.

MitigationUpdate to the latest plugin version if available; otherwise disable the plugin until a patch is released. Review admin actions for proper nonce implementation.

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 Appsero Helper plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and search for 'Appsero Helper' or check the wp-content/plugins directory for an appsero-helper folder
    Affected if The Appsero Helper plugin is present in the WordPress installation
  2. Check installed plugin version
    In WordPress admin > Plugins > Installed Plugins, find Appsero Helper and note the version number displayed. Alternatively, read the main plugin PHP file header or check the plugin's readme.txt for the Version field
    Affected if Version is 1.3.2 or lower (any version up to and including 1.3.2)
  3. Identify the vulnerable admin page
    Check for the existence of the appsero_helper admin page by reviewing plugin menu registrations in the WordPress admin or inspecting plugin files for add_menu_page or add_submenu_page calls referencing 'appsero_helper'
    Affected if The appsero_helper admin page is registered and accessible in the WordPress admin panel
  4. Verify nonce validation is missing
    Review the PHP handler for the appsero_helper admin page (typically in the plugin's main file or admin subdirectory). Look for wp_verify_nonce or check_admin_referer calls at the start of any form processing or action handling code
    Affected if No nonce verification (wp_verify_nonce, check_admin_referer, or similar) is found in the admin page's action handler code

A user is affected if the Appsero Helper plugin is installed with version 1.3.2 or lower and the appsero_helper admin page exists without proper nonce validation on admin actions.
