AI-suggested

A fix is available in LiquidJS version 10.25.7. Users and administrators should upgrade to version 10.25.7 or later to remediate this vulnerability. Since this is a self-hosted library, patching the dependency in affected applications is required. No other mitigations are indicated.

Description

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.7, a circular block reference in {% layout %} / {% block %} causes an infinite recursive loop, consuming all available memory (~4GB) and crashing the Node.js process with FATAL ERROR: JavaScript heap out of memory. This allows any user who can submit a Liquid template to perform a Denial of Service attack. This issue has been patched in version 10.25.7.
