CVE-2026-11783Public exploitNetwork attack vector

Stored XSS via unescaped product SKU

Published Jun 27, 2026 · Updated Jun 27, 2026

Stored cross-site scripting in weDevs Dokan Multivendor 5.0.4 and earlier allows remote authenticated users to inject scripts via product SKUs. The store search response returns vendor-controlled SKU markup without output escaping, and the search widget inserts that HTML into the DOM with jQuery's .html() method. Custom-level vendor access is sufficient to store a payload that executes in visitors' browsers, including unauthenticated visitors who use the affected search.
