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-2026-33285: 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...
