Vulnerabilities

The WPML plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpml_language_switcher shortcode in versions 3.6.0 - 4.7.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WPML plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.6.12 via Twig Server-Side Template Injection. This is due to missing input validation and sanitization on the render function. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute code on the server.
