CVE-2026-5226 Details
Description
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.
A reflected cross-site scripting vulnerability has been identified in the Optimole WordPress plugin, specifically in versions through 4.2.3. The issue arises from inadequate output escaping of user-supplied URL paths in the 'get_current_url()' function. These paths are inserted into JavaScript code via 'str_replace()' without proper escaping for JavaScript context in the 'replace_content()' function. This vulnerability allows unauthenticated attackers to inject arbitrary web scripts into pages, which could be executed if the victim is tricked into clicking a link.
Users are advised to update the Optimole WordPress plugin to version 4.2.4 or later, where this vulnerability has been patched.
