Description

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.

Recommendation

Update the liquidjs package to the latest compatible version. Followings are version details:

  • Affected version(s): <= 10.27.1
  • Patched version(s): 10.27.2
