Descriptions

The WebP & SVG Support WordPress plugin through 1.4.0 does not sanitise uploaded SVG files, which could allow users with a role as low as Author to upload a malicious SVG containing XSS payloads.

El complemento WebP & SVG Support de WordPress hasta la versión 1.4.0 no sanitiza los archivos SVG cargados, lo que podría permitir a los usuarios con un rol tan bajo como Autor cargar un SVG malicioso que contenga payloads XSS.

The WebP & SVG Support plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 1.4.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
