LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.27.1, the pop array filter at src/filters/array.ts allocated a full clone of its input array via [...toArray(v)] without calling this.context.memoryLimit.use(...), allowing a template render such as {{ huge array | pop }} to allocate an O(N) clone of an attacker-influenced array outside the configured memoryLimit budget. This issue is fixed in version 10.27.1.
