Arbitrary File Access in LiquidJS Template Engine Prior to

Publication date: 2026-03-10

Last updated on: 2026-03-18

Assigner: GitHub, Inc.

Description
liquidjs is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.25.0, the layout, render, and include tags allow arbitrary file access via absolute paths (either as string literals or through Liquid variables, the latter require dynamicPartials: true, which is the default). This poses a security risk when malicious users are allowed to control the template content or specify the filepath to be included as a Liquid variable. This vulnerability is fixed in 10.25.0.

Executive Summary

The vulnerability exists in liquidjs, a JavaScript template engine compatible with Shopify and GitHub Pages. Before version 10.25.0, the layout, render, and include tags allowed arbitrary file access using absolute paths. This could happen either through string literals or Liquid variables (when dynamicPartials is enabled, which is the default).

If a malicious user can control the template content or specify the filepath as a Liquid variable, they could exploit this to access arbitrary files on the system.

This security risk was addressed and fixed in version 10.25.0 of liquidjs.

Impact Analysis

This vulnerability can lead to unauthorized access to arbitrary files on the server where liquidjs is used. If exploited, an attacker could read sensitive files, potentially exposing confidential information or system data.

Since the vulnerability allows file access without any privileges or user interaction, it poses a high security risk.
