CVE-2026-30952 (GCVE-0-2026-30952)

Vulnerability from cvelistv5 – Published: 2026-03-10 20:25 – Updated: 2026-03-11 14:39

Title

liquidjs has a path traversal fallback vulnerability

Summary

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.

Severity ?

8.7 (High)

Vulnerability from github – Published: 2026-03-10 01:04 – Updated: 2026-03-12 14:25

Summary

liquidjs has a path traversal fallback vulnerability

Details

Impact

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.

Patches

The root cause is LiquidJS allows require.resolve() as fallback but doesn't limit the directories it can resolve to. The issue is fixed via #855 and published version 10.25.0 on npm.

Workarounds

Change the files in build time

In build time, through Shell script or Webpack string-replace-loader, change the file content of correxponding file (depending on your package type, for CommonJS it's dist/liquid.node.js) under dist/,

  if (fs.fallback !== undefined) {
    const filepath = fs.fallback(file)
-   if (filepath !== undefined) yield filepath
+   if (filepath !== undefined) {
+     for (const dir of dirs) {
+       if (!enforceRoot || this.contains(dir, filepath)) {
+         yield filepath
+         break
+       }
+     }
    }
  }

Overriding by `fs` LiquidJS option

Adding a fs option to override the default fs implementation:

const { statSync, readFileSync, promises: { stat, readFile } } = require('fs')
const { resolve, extname, dirname, sep } = require('path')

const fs = {
    exists: async (fp) => { try { await stat(fp); return true; } catch { return false } },
    existsSync: (fp) => { try { statSync(fp); return true } catch { return false } },
    resolve: (root, file, ext) => resolve(root, file + (extname(file) ? '' : ext)),
    contains: (root, file) => {
        const r = resolve(root)
        return file.startsWith(r.endsWith(sep) ? r : r + sep)
    },
    readFile: (fp) => readFile(fp, 'utf8'),
    readFileSync: (fp) => readFileSync(fp, 'utf8'),
    fallback: () => undefined,
    dirname,
    sep
};

const engine = new Liquid({ fs })
