Prior to 4.5.2, applications that pass user-controlled input to Handlebars.compile() using FileTemplateLoader or ClassPathTemplateLoader are vulnerable to path traversal, allowing arbitrary file read through template names derived from URL path parameters, request parameters, or other user-controlled sources. This issue is fixed in version 4.5.2."

Antes de la versión 4.5.2, las aplicaciones que pasan entradas controladas por el usuario a Handlebars.compile() usando FileTemplateLoader o ClassPathTemplateLoader son vulnerables a salto de ruta, permitiendo la lectura arbitraria de archivos a través de nombres de plantillas derivados de parámetros de ruta de URL, parámetros de solicitud u otras fuentes controladas por el usuario. Este problema está solucionado en la versión 4.5.2."
