NewCVE-2026-106120 (opens in a new tab)How to fix?
Upgrade liquidjs to version 10.27.2 or higher.
Overview
liquidjs is an A simple, expressive, safe and Shopify compatible template engine in pure JavaScript.
Affected versions of this package are vulnerable to Incorrect Authorization via array index access in the readArrayElement path, where the ownPropertyOnly option is not enforced for negative indices, first/last property access, and the first/last filters. An authenticated attacker can supply a template that accesses prototype-inherited array indices, bypassing the ownPropertyOnly restriction and reading values from the prototype chain that should be hidden.
Note: This is only exploitable when the ownPropertyOnly option is explicitly enabled.
