Descriptions

The Oxygen Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a custom field in all versions up to, and including, 4.8 due to insufficient input sanitization and output escaping. 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. NOTE: Version 4.8.1 of the Oxygen Builder plugin for WordPress addresses this vulnerability by implementing an optional filter to provide output escaping for dynamic data. Please see https://oxygenbuilder.com/documentation/other/security/#filtering-dynamic-data for more details.

El complemento Oxygen Builder para WordPress es vulnerable a Cross-Site Scripting almacenado a través de un campo personalizado en todas las versiones hasta la 4.8 inclusive debido a una sanitización de entrada y un escape de salida insuficientes. Esto hace posible que atacantes autenticados, con acceso de nivel de colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. NOTA: La versión 4.8.1 del complemento Oxygen Builder para WordPress aborda esta vulnerabilidad implementando un filtro opcional para proporcionar salida de escape para datos dinámicos. Consulte https://oxygenbuilder.com/documentation/other/security/#filtering-dynamic-data para obtener más detalles.
