CVE-2026-39859 Details
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.
A vulnerability in LiquidJS versions through 10.25.4 allows arbitrary file reading. The issue arises because top-level file loads do not properly enforce the 'root' directory constraint, which is intended to limit file access. As a result, a Liquid instance with an empty temporary directory as root can be manipulated to read and return the contents of any file accessible to the server process.
Users are advised to update to LiquidJS version 10.25.3 or later, where this vulnerability has been fixed.
