LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript.

Applications relying on ownPropertyOnly: true as a security boundary (e.g., multi-tenant template systems) are exposed to information disclosure of sensitive prototype properties such as API keys and tokens. This vulnerability is fixed in 10.25.4.
