 "title": "eCommerce Product Catalog <= 3.6.4 - Unauthenticated Reflected Cross-Site Scripting via 'ic-search-keyword' esc_html Filter Bypass",
 "description": "The eCommerce Product Catalog plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'ic-search-keyword' esc_html filter bypass in all versions up to, and including, 3.6.4, due to the plugin hooking the global 'esc_html' filter and returning the original, unescaped text whenever it contains the string 'ic-search-keyword'. This turns off esc_html() escaping across the whole site, in WordPress core and in other plugins and themes, for any attacker-supplied value that contains that string. This makes it possible for unauthenticated attackers to inject arbitrary web scripts into pages that execute if they can trick a user, such as an administrator, into performing an action such as clicking on a link.",
