CVE-2026-30952
liquidjs has a path traversal fallback vulnerability
HIGH 8.7EPSS 0.6%
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.
