CVE-2026-34166

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.25.3, the replace filter in LiquidJS incorrectly accounts for memory usage when the memoryLimit option is enabled.

CVE-2026-34166

LiquidJS (template engine) has a memoryLimit bypass in the replace filter: when memoryLimit is enabled, replacing a pattern can produce output size that grows quadratically with occurrences, bypassing the configured memory cap and risking out-of-memory DoS. Affected: prior to 10.25.3. Fix: upgrad...

LiquidJS: Root restriction bypass for partial and layout loading through symlinked templates

Summary LiquidJS enforces partial and layout root restrictions using the resolved pathname string, but it does not resolve the canonical filesystem path before opening the file. A symlink placed inside an allowed partials or layouts directory can therefore point to a file outside that directory a...
