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) Shoppette 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

The Easy Digital Downloads (EDD) Shoppette theme for WordPress contains a Cross-Site Scripting (XSS) vulnerability due to improper use of the add_query_arg function. The function constructs URLs with query parameters, but when these URLs are output without proper escaping (e.g., using esc_url() or esc_attr()), malicious script can be injected via the query parameters.

MitigationUpdate Easy Digital Downloads 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 the fix for the add_query_arg misuse. Alternatively, ensure all add_query_arg() outputs are properly escaped with esc_url() or esc_attr() before rendering.
