LiquidJS: Uncontrolled Resource Consumption in `join` filter allows template authors to bypass `memoryLimit` and crash the process

Summary The join filter src/filters/array.ts:8-13 charges memoryLimit by array element count, not by the string length it produces, letting a template bypass a configured memoryLimit and allocate strings far past budget — bounded only by V8/process limits, not by memoryLimit. Details js //...

CVE-2026-69222

LiquidJS versions prior to 10.27.2 have a memory-limit accounting defect in the join and array_to_sentence_string filters: they bill complexity by element count rather than output string length, so a crafted template can allocate toward V8's memory limits and crash the process. Exploitation requi...

CVE-2026-69222 LiquidJS: Uncontrolled Resource Consumption in `join` filter allows template authors to bypass `memoryLimit` and crash the process

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.27.2, the join filter in src/filters/array.ts computes complexity from array.length and separator length instead of the total string length produced by array.joinsep. The concat filter can cheaply doub...

CVE-2026-55575: Allocation of Resources Without Limits or Throttling

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.27.1, the pop array filter at src/filters/array.ts allocated a full clone of its input array via ...toArrayv without calling this.context.memoryLimit.use..., allowing a template render such as hugearra...

CVE-2026-34166: Uncontrolled Resource Consumption

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. It charges str.length + pattern.length + replacement.length bytes to the memory limite...

CVE-2026-33285: Improper Input Validation

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, LiquidJS's memoryLimit security mechanism can be completely bypassed by using reverse range expressions e.g., 100000000..1, allowing an attacker to allocate unlimited memory. Combined wit...

shopify-scripts: Read after free in mrb_vm_exec with OP_ARYCAT reading R(B)

Hi, Slightly different one, this is a use after free as reported by an ASAN compiled binary. This one doesn't affect mruby-engine with the current instruction limit and memory limit, but if they are increased then it does. The file is: class Klazz def $thing.name [email protected]@thing.name nil end...
