WPML Multilingual CMS plugin for WordPress before 4.6.1 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject script by supplying crafted input in the wp_lang parameter. Attackers can lure users to /wp-login.php with a wp_lang value injecting an image input with an obfuscated onfocus handler to execute JavaScript in the victim's browser. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-11-12.
