CVE-2026-39412

CVE-2026-39412 · LiquidJS has an ownPropertyOnly bypass via sort_natural filter — prototype property information disclosure through sorting side-channel

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
