Vulnerability Title
LiquidJS has a renderFile() / parseFile() bypass configured root and allow arbitrary file read
Source: NVD (National Vulnerability Database)
Vulnerability Description
LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.25.3, liquidjs 10.25.0 documents root as constraining filenames passed to renderFile() and parseFile(), but top-level file loads do not enforce that boundary. A Liquid instance configured with an empty temporary directory as root can return the contents of arbitrary files. This vulnerability is fixed in 10.25.3.
