CVE-2026-41311: CWE-674: Uncontrolled Recursion in harttle liquidjs
CVE-2026-41311 is a high-severity vulnerability in the harttle liquidjs template engine prior to version 10. 25. 7. It involves uncontrolled recursion caused by circular block references in {% layout %} / {% block %} tags, leading to an infinite loop that exhausts memory and crashes the Node. js process. This enables any user able to submit a Liquid template to cause a denial of service (DoS). The issue has been fixed in version 10. 25. 7.
AI Analysis
Technical Summary
LiquidJS versions before 10.25.7 contain a vulnerability (CWE-674) where circular references in template blocks cause infinite recursion. This recursion consumes all available memory (~4GB), resulting in a fatal out-of-memory crash of the Node.js process. The vulnerability allows unauthenticated users who can submit templates to trigger a denial of service. The vendor has patched this issue in version 10.25.7.
Potential Impact
Successful exploitation results in a denial of service by crashing the Node.js process running LiquidJS due to heap memory exhaustion. There is no impact on confidentiality or integrity, only availability is affected.
Mitigation Recommendations
Upgrade to LiquidJS version 10.25.7 or later, where this uncontrolled recursion vulnerability has been patched. No other mitigation is indicated or required.
