Descriptions

The Post Grid Combo – 36+ Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the custom JS parameter in all versions up to, and including, 2.2.64 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access or higher to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

El complemento Post Grid Combo – 36+ Gutenberg Blocks para WordPress es vulnerable a Cross-Site Scripting almacenado a través del parámetro JS personalizado en todas las versiones hasta la 2.2.64 incluida debido a una sanitización de entrada y un escape de salida insuficientes. Esto hace posible que atacantes autenticados, con acceso de colaborador o superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada.
