CVE-2026-39412

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.25.4, the sortnatural filter bypasses the ownPropertyOnly security option, allowing template authors to extract values of prototype-inherited properties through a sorting side-channel attack...

GHSA-R7G9-XPMJ-5FCQ LiquidJS Vulnerable to ReDoS via Quadratic Backtracking in `strip_html` Filter Regex

Summary The built-in striphtml filter in liquidjs uses a regex containing four lazy-quantified alternatives. When the input contains many |||/g, '' The regex contains four lazy patterns: 1. 2. 3. 4. For an input like 'script'.repeatN, the engine encounters N starting positions. At each one it mus...

GHSA-HH27-HF48-9F5Q LiquidJS has a memory and render limit bypass via unbounded width padding in `date` filter (strftime)

Summary The date filter's strftime implementation parses width specifiers like %9999999d and forwards the captured width unchecked into pad/padStart in src/util/underscore.ts. The pad loop performs unbounded string concatenation without consulting the Context's memoryLimit or renderLimit, so a...

GHSA-9X9P-QF8F-MVJG LiquidJS's `{% render %}` tag silently bypasses per-render `ownPropertyOnly:true` via `Context.spawn()`

Summary Context.spawn in liquidjs creates a child Context for the % render % tag but does not propagate the parent context's resolved ownPropertyOnly value. The new context re-derives ownPropertyOnly from opts.ownPropertyOnly the instance-level option, silently discarding any...

GHSA-8XX9-69P8-7JP3 LiquidJS has a renderLimit DoS guard bypass via empty `{% for %}` body

Summary The renderLimit option — documented in docs/source/tutorials/dos.md as the mechanism that "mitigates this by limiting the time consumed by each render call" — can be fully bypassed by a % for % or % tablerow % tag whose body is empty. The per-iteration time check is reached only when the...
