Vulnerability Overview

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.

Technical Analysis

REMEDIATION: Update to version 4.6.13, or a newer patched version --- IDENTIFIER: CWE-1336 (Improper Neutralization of Special Elements Used in a Template Engine) 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.
