CVE-2026-62992

Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. Prior to 5.8.2 (and 4.5.7 on the 4.x line), Security::_checkDir() does not fully resolve symbolic links before validating that a requested path lies within a configured secure directory. An attacker able to place or reference a symlink within a directory Smarty treats as trusted (e.g., a template or config directory) could use it to point outside the intended secure directory, bypassing the containment check and reading arbitrary files accessible to the PHP process. This issue is fixed in versions 5.8.2 and 4.5.7.

Summary		(es) Smarty es un motor de plantillas para PHP, que facilita la separación de la presentación (HTML/CSS) de la lógica de la aplicación. Antes de la versión 5.8.2 (y 4.5.7 en la línea 4.x), Security::_checkDir() no resuelve completamente los enlaces simbólicos antes de validar que una ruta solicitada se encuentra dentro de un directorio seguro configurado. Un atacante capaz de colocar o referenciar un enlace simbólico dentro de un directorio que Smarty considera de confianza (por ejemplo, un directorio de plantillas o de configuración) podría usarlo para apuntar fuera del directorio seguro previsto, eludiendo la comprobación de contención y leyendo archivos arbitrarios accesibles al proceso PHP. Este problema está solucionado en las versiones 5.8.2 y 4.5.7.
