Summary
Vulnerability in LiquidJS before version 10.25.4, where the sort_natural filter bypasses the ownPropertyOnly security option. This allows template authors to extract values of prototype-inherited properties through a sorting side-channel attack.
Risk Assessment
In multi-tenant systems relying on ownPropertyOnly: true as a security boundary, attackers can access sensitive prototype properties such as API keys and tokens.
Recommendation
Update LiquidJS to version 10.25.4.
Original NVD description (English source)
LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.25.4, the sort_natural filter bypasses the ownPropertyOnly security option, allowing template authors to extract values of prototype-inherited properties through a sorting side-channel attack. Applications relying on ownPropertyOnly: true as a security boundary (e.g., multi-tenant template systems) are exposed to information disclosure of sensitive prototype properties such as API keys and tokens. This vulnerability is fixed in 10.25.4.
