The Optimole – Optimize Images in Real Time plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL paths in versions up to, and including, 4.2.3 This is due to insufficient output escaping on user-supplied URL paths in the get_current_url() function, which are inserted into JavaScript code via str_replace() without proper JavaScript context escaping in the replace_content() function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
