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) Wish Lists extension 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

The Easy Digital Downloads (EDD) Wish Lists extension for WordPress contains a cross-site scripting (XSS) vulnerability caused by improper use of the add_query_arg function. The function builds URLs but does not escape output; when developers fail to apply escaping functions like esc_url() or esc_attr() when rendering the generated URL, malicious input can be injected and executed in user browsers.

MitigationUpdate the EDD Wish Lists extension to one of the patched versions (1.8.7, 1.9.10, 2.0.5, 2.1.11, 2.2.9, or 2.3.7 or later) to resolve the XSS vulnerability.

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 EDD Wish Lists extension is installed
    Navigate to WordPress admin > Plugins and look for 'Easy Digital Downloads - Wish Lists' or 'EDD Wish Lists' in the installed plugins list
    Affected if The plugin appears in the installed plugins list and is activated
  2. Check the installed Wish Lists version
    In WordPress admin > Plugins, find the EDD Wish Lists entry and note the version number displayed
    Affected if The version is any version (all versions of the Wish Lists extension are affected)
  3. Verify Easy Digital Downloads core plugin version
    In WordPress admin > Plugins, locate the 'Easy Digital Downloads' core plugin and note its version number
    Affected if The version falls within any of these 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; >=2.3 and <2.3.7
  4. Inspect plugin files for vulnerable add_query_arg usage
    Access the plugin files via FTP or file manager, locate the Wish Lists extension files (typically in wp-content/plugins/edd-wish-lists/), and search for add_query_arg calls that lack esc_url() or esc_attr() wrapping when outputting URLs
    Affected if Code contains add_query_arg() being echoed or printed without proper escaping functions like esc_url() or esc_attr() applied to the output

If the EDD Wish Lists extension is installed and active, the environment is affected since all versions of this extension contain the XSS vulnerability, regardless of the core EDD version.
