Descriptions

The package handlebars before 4.7.7 are vulnerable to Remote Code Execution (RCE) when selecting certain compiling options to compile templates coming from an untrusted source.

El paquete handlebars versiones anteriores a 4.7.7, son vulnerables a una Ejecución de Código Remota (RCE) al seleccionar determinadas opciones de compilación para compilar plantillas que provienen de una fuente no confiable

A flaw was found in nodejs-handlebars. A missing check when getting prototype properties in the template function allows an attacker, who can provide untrusted handlebars templates, to execute arbitrary code in the javascript system (e.g. browser or server) when the template is compiled with the strict:true option. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
