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 Easy Digital Downloads (EDD) Lattice theme for WordPress, as used with EDD 1.8.x before 1.8.7, 1.9.x before 1.9.10, 2.0.x before 2.0.5, 2.1.x before 2.1.11, 2.2.x before 2.2.9, and 2.3.x before 2.3.7, has XSS because add_query_arg is misused.

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

This is a Cross-Site Scripting (XSS) vulnerability in the Easy Digital Downloads (EDD) WordPress plugin's Lattice theme. The vulnerability stems from the misuse of WordPress's add_query_arg() function, which constructs URLs but does not automatically escape output for safe HTML rendering. When these URLs are rendered without proper escaping (e.g., using esc_url() or esc_attr()), malicious scripts can be injected via crafted query parameters.

MitigationUpdate EDD to version 1.8.7, 1.9.10, 2.0.5, 2.1.11, 2.2.9, or 2.3.7 or later, which contain proper URL escaping for add_query_arg() calls. Alternatively, ensure all add_query_arg() output is wrapped with esc_url() or esc_attr() before rendering.

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 Easy Digital Downloads plugin is installed
    Locate the EDD plugin directory in your WordPress installation, typically at wp-content/plugins/easy-digital-downloads, or check the Plugins page in WordPress admin.
    Affected if The plugin directory exists and the plugin is active.
  2. Identify the installed EDD version
    Open the main EDD plugin file (usually easy-digital-downloads.php) and locate the 'Version:' header in the plugin comments, or check the WordPress Plugins admin page for the installed version number.
    Affected if The version falls within any of these vulnerable ranges: >= 1.8 and < 1.8.7; >= 1.9 and < 1.9.10; >= 2.0 and < 2.0.5; >= 2.1 and < 2.1.11; >= 2.2 and < 2.2.9; or >= 2.3 and < 2.3.7.
  3. Verify if Lattice theme is active
    Check your WordPress appearance/themes section to see if the Lattice theme is currently active, or inspect the wp-content/themes/lattice directory.
    Affected if The Lattice theme is currently active on the WordPress site.
  4. Inspect for unescaped add_query_arg usage
    Search the EDD plugin files for add_query_arg() function calls and verify whether the output is wrapped with esc_url() or esc_attr() before being echoed or rendered. Specifically look for patterns like 'echo add_query_arg(...)' without escaping functions.
    Affected if Any add_query_arg() output is rendered without esc_url() or esc_attr() escaping, allowing malicious query parameters to execute as JavaScript.

Your environment is affected if Easy Digital Downloads plugin is installed with a vulnerable version (as listed above) OR if the Lattice theme is active, and unescaped add_query_arg() calls exist in the code that could render malicious scripts via URL query parameters.
