NewCVE-2026-45357 (opens in a new tab)How to fix?
Upgrade liquidjs to version 10.26.0 or higher.
Overview
liquidjs is an A simple, expressive, safe and Shopify compatible template engine in pure JavaScript.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the date filter in filters/date.ts and the strftime formatter in strftime.ts. An attacker can exhaust memory or hang rendering by supplying a crafted date format string that includes extremely large numeric width directives or non-string format values that expand into large padding allocations.
The vulnerable code builds padding one character at a time and does not account for the allocation cost of strftime width handling in its memory accounting path, so a user-controlled template or data value can drive unbounded allocation work during date formatting. This can crash the process or make the application unresponsive while rendering attacker-controlled templates.
