The WPML plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.6.12 via the 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.
The product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine.
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
