Prior to version 1.7.45, due to the unrestricted access to twig extension class from Grav context, an attacker can redefine config variable. As a result, attacker can bypass a previous SSTI mitigation. Twig processing of static pages can be enabled in the front matter by any administrative user allowed to create or edit pages. As the Twig processor runs unsandboxed, this behavior can be used to gain arbitrary code execution and elevate privileges on the instance. Version 1.7.45 contains a fix for this issue.\n"}, {"lang": "es", "value": "Grav es un sistema de gesti\u00f3n de contenidos de archivos planos de c\u00f3digo abierto.
