CVE-2026-62996

Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. From 5.0.0 until 5.8.4, Smarty's stream: resource-name handling does not adequately restrict which PHP stream wrappers and filter chains can be referenced from a template, allowing a php://filter-wrapped resource name to be used to read the contents of arbitrary local files accessible to the PHP process. An attacker able to author or influence a template's resource reference could exploit this to disclose sensitive file contents outside the intended template/config scope. This issue is fixed in version 5.8.4.

Summary		(es) Smarty es un motor de plantillas para PHP, facilitando la separación de la presentación (HTML/CSS) de la lógica de la aplicación. Desde la versión 5.0.0 hasta la 5.8.4, el manejo de ’stream: resource-name’ de Smarty no restringe adecuadamente qué envoltorios de flujo de PHP y cadenas de filtros pueden ser referenciados desde una plantilla, permitiendo que un nombre de recurso envuelto en ’php://filter’ sea utilizado para leer el contenido de archivos locales arbitrarios accesibles al proceso PHP. Un atacante capaz de crear o influenciar la referencia de un recurso de plantilla podría explotar esto para divulgar contenido de archivos sensibles fuera del alcance previsto de la plantilla/configuración. Este problema está corregido en la versión 5.8.4.
