Is this vulnerability remotely exploitable?

Yes, if an attacker can supply or significantly influence the LiquidJS template content processed by the server. A single malicious template rendered via an HTTP request can be enough to cause a denial of service.

What level of access does an attacker need?

The attacker needs the ability to inject or control templates or template fragments, such as through user-editable pages, email templates, or configuration fields that are rendered using LiquidJS. Direct system or file-level access is not required if the application exposes such templating surfaces over the network.

What is the safest general fix pattern?

The safest pattern is to combine a robust, comprehensive resource-limiting strategy with strict control over which Liquid constructs are allowed. This means ensuring that ranges (including reverse ranges), loops, and expensive filters are all covered by the same consistent limits, and that dangerous patterns are rejected before rendering.
