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
Cross-Site Request Forgery (CSRF) vulnerability in Essential Marketer Essential Breadcrumbs essential-breadcrumbs allows Stored XSS.This issue affects Essential Breadcrumbs: from n/a through <= 1.1.1.

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

Cross-Site Request Forgery (CSRF) vulnerability in the Essential Breadcrumbs WordPress plugin allows remote attackers to inject malicious JavaScript code (Stored XSS) through crafted requests. The lack of proper CSRF token validation enables attackers to trick authenticated administrators into executing unintended actions that store malicious scripts in the database, which then executes when other users view the affected pages.

MitigationImplement WordPress nonces and CSRF token validation on all form submissions and admin actions, combined with proper input sanitization and output encoding to prevent XSS. Update to a patched version if released by the vendor.

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 Essential Breadcrumbs plugin is installed
    Go to WordPress Admin > Plugins and look for 'Essential Breadcrumbs' in the installed plugins list, or query the wp_options table for option_name = 'active_plugins' and check for the plugin entry
    Affected if The plugin is installed and active
  2. Identify the installed plugin version
    In Plugins list view, click on the plugin to view details and note the version number, or check the plugin main file header in wp-content/plugins/essential-breadcrumbs/ for the Version: X.X.X comment
    Affected if The version is unknown, unpatched, or no security patch has been applied to address CSRF token validation
  3. Confirm the plugin is processing user-supplied breadcrumb settings
    Check if breadcrumb settings (such as separator, prefix, suffix, or custom breadcrumb templates) can be saved through the plugin admin interface at Settings > Essential Breadcrumbs or a related admin page
    Affected if The plugin admin interface allows saving breadcrumb configuration without requiring nonce/token validation
  4. Inspect saved breadcrumb options for suspicious content
    Query the wp_options table for option_name containing 'breadcrumb' (e.g., SELECT option_value FROM wp_options WHERE option_name LIKE '%breadcrumb%') and examine the stored values for unexpected script tags, iframe tags, or javascript: URIs
    Affected if Stored breadcrumb options contain unencoded JavaScript, script tags, or event handler attributes that could execute as Stored XSS

You are affected if the Essential Breadcrumbs plugin is active, lacks proper CSRF/nonce validation on its admin settings forms, and malicious script payloads have been stored in breadcrumb configuration options in the database.
