liquidjs is vulnerable to Remote Code Execution (RCE)
92
Critical Risk
This Affects:
liquidjsTL;DR
The engine kept filter and tag registries on ordinary objects, so template-controlled names like valueOf or constructor resolved to inherited Object.prototype members. Invoking those names through the filter pipeline could return internal objects and expose parser, loader, and context state, with a confirmed chain to arbitrary code execution. Registries now use null-prototype objects so only explicitly registered filters and tags are reachable. Regression tests cover inherited names as filters and tags.
