Description Preview

A resource exhaustion vulnerability (CWE-400) was discovered in the StaticPool component of node-worker-threads-pool version 1.4.3. This vulnerability allows attackers to cause a denial of service condition by consuming excessive system resources, potentially making the application or system unresponsive.

Overview

The vulnerability exists in the StaticPool implementation of the node-worker-threads-pool library version 1.4.3. The issue allows attackers to trigger excessive resource consumption, leading to a denial of service condition. This occurs because the StaticPool component does not properly manage system resources under certain conditions, allowing an attacker to exhaust available resources and potentially crash the application or make it unresponsive. Applications using this library for worker thread management are vulnerable if they implement the StaticPool feature.

Remediation

Users should upgrade to a patched version of node-worker-threads-pool if available. If upgrading is not immediately possible, consider implementing the following mitigations:

  1. Monitor and limit resource usage of applications using the StaticPool component
  2. Implement additional error handling and resource management around StaticPool usage
  3. Consider implementing application-level timeouts and resource limits
  4. If possible, switch to alternative thread pool implementations until a patch is available
