CVE-2026-69222: CWE-400: Uncontrolled Resource Consumption in harttle liquidjs
CVE-2026-69222 is a high-severity vulnerability in the harttle liquidjs template engine prior to version 10.27.2. The issue involves uncontrolled resource consumption due to improper accounting of string length in the join and array_to_sentence_string filters. This flaw allows crafted templates to exceed configured memory limits, potentially causing process crashes.
AI Analysis
Technical Summary
LiquidJS, a JavaScript template engine compatible with Shopify and GitHub Pages, has a vulnerability in versions before 10.27.2 where the join filter calculates complexity based on array length and separator length rather than the total string length produced by array.join(sep). The concat filter can double arrays of references cheaply, and join materializes the referenced content while charging only for element count. Similarly, the array_to_sentence_string filter suffers from the same accounting defect. This allows a crafted template to allocate excessive memory, potentially reaching V8's string or process memory limits and crashing the process. The issue is fixed in version 10.27.2.
Potential Impact
An attacker can craft templates that cause excessive memory allocation, leading to process crashes due to uncontrolled resource consumption. This impacts availability but does not affect confidentiality or integrity.
Mitigation Recommendations
Upgrade to liquidjs version 10.27.2 or later, where this issue is fixed. No other mitigation is indicated or required.
