CVE-2026-45017

Python Liquid is a Python engine for the Liquid template language. Prior to 2.2.0, the built-in FileSystemLoader and CachingFileSystemLoader do not guard against reading files outside their search paths when given an absolute path to resolve. This allows malicious template authors to load and render arbitrary files via the {% include %} and {% render %} tags. Targeted files would need to contain valid Liquid markup and be readable by the application process. This vulnerability is fixed in 2.2.0.

Summary		(es) Python Liquid es un motor de Python para el lenguaje de plantillas Liquid. Antes de la versión 2.2.0, los cargadores integrados FileSystemLoader y CachingFileSystemLoader no impiden la lectura de archivos fuera de sus rutas de búsqueda cuando se les proporciona una ruta absoluta para resolver. Esto permite a autores de plantillas maliciosos cargar y renderizar archivos arbitrarios a través de las etiquetas {% include %} y {% render %}. Los archivos objetivo necesitarían contener marcado Liquid válido y ser legibles por el proceso de la aplicación. Esta vulnerabilidad está corregida en la versión 2.2.0.
