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...

LiquidJS: ownPropertyOnly bypass for inherited array indices in first/last/join/reverse/slice/compact, `.first`/`.last`, negative index, and for-loop iteration

Summary LiquidJS’s ownPropertyOnly option is intended to prevent templates from reading inherited or prototype properties from scope data. With ownPropertyOnly: true, direct access such as: liquid a0 correctly blocks an inherited array index. However, the same inherited value is still disclosed...
