Descriptions

The URL Shortify WordPress plugin before 1.7.6 does not properly escape the value of the referer header, thus allowing an unauthenticated attacker to inject malicious javascript that will trigger in the plugins admin panel with statistics of the created short link.

El complemento URL Shortify de WordPress anterior a 1.7.6 no escapa correctamente del valor del encabezado de referencia, lo que permite que un atacante no autenticado inyecte javascript malicioso que se activará en el panel de administración del complemento con estadísticas del enlace creado.

The URL Shortify plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the referrer header in versions up to, and including, 1.7.5 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.
