Prior to 10.25.3, for {% include %}, {% render %}, and {% layout %}, LiquidJS checks whether the candidate path is inside the configured partials or layouts roots before reading it. That check is path-based, not realpath-based. Because of that, a file like partials/link.liquid passes the directory containment check as long as its pathname is under the allowed root. If link.liquid is actually a symlink to a file outside the allowed root, the filesystem follows the symlink when the file is opened and LiquidJS renders the external target. So the restriction is applied to the path string that was requested, not to the file that is actually read. This matters in environments where an attacker can place templates or otherwise influence files under a trusted template root, including uploaded themes, extracted archives, mounted content, or repository-controlled template trees. This vulnerability is fixed in 10.25.3."}, {"lang": "es", "value": "LiquidJS es un motor de plantillas compatible con Shopify / GitHub Pages en JavaScript puro. Antes de la versi\u00f3n 10.25.3, para {% include %}, {% render %} y {% layout %}, LiquidJS verifica si la ruta candidata est\u00e1 dentro de las ra\u00edces de parciales o dise\u00f1os configuradas antes de leerla. Esa verificaci\u00f3n se basa en la ruta, no en la ruta real. Debido a eso, un archivo como partials/link.liquid pasa la verificaci\u00f3n de contenci\u00f3n de directorio siempre que su nombre de ruta est\u00e9 bajo la ra\u00edz permitida. Si link.liquid es en realidad un enlace simb\u00f3lico a un archivo fuera de la ra\u00edz permitida, el sistema de archivos sigue el enlace simb\u00f3lico cuando se abre el archivo y LiquidJS renderiza el objetivo externo. As\u00ed, la restricci\u00f3n se aplica a la cadena de ruta que fue solicitada, no al archivo que realmente se lee. Esto importa en entornos donde un atacante puede colocar plantillas o influir de otra manera en archivos bajo una ra\u00edz de plantilla de confianza, incluyendo temas subidos, archivos extra\u00eddos, contenido montado o \u00e1rboles de plantillas controlados por repositorio.
