Descriptions

The Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘alt’ parameter in all versions up to, and including, 2.9.1.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

El complemento Gravity Forms para WordPress es vulnerable a Cross-Site Scripting almacenado a través del parámetro "alt" en todas las versiones hasta la 2.9.1.3 incluida debido a una desinfección de entrada y un escape de salida insuficientes. Esto hace posible que atacantes no autenticados inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada.
