Upgrade LiquidJS to version 10.25.4 or later, where this vulnerability is fixed.
Description
A vulnerability in LiquidJS versions prior to 10.25.4 allows template authors to bypass the ownPropertyOnly security option via the sort_natural filter. This enables unauthorized exposure of sensitive prototype-inherited properties, such as API keys and tokens, through a sorting side-channel attack. The issue is fixed in version 10.25.4.
