Mitigation checklist

Recommended fix / mitigation
  • Do not pass untrusted or user-controlled input to brace-expansion's expand() function or to libraries that use it for glob pattern matching (such as minimatch or glob). Validate and sanitize any brace patterns before expansion. Where possible, upgrade to brace-expansion 1.1.17, 2.1.3, 3.0.3, or 5.0.8 which add a maxLength option that bounds accumulated output. As an additional defense-in-depth measure, enforce memory limits on Node.js processes using operating system resource controls such as cgroups or Kubernetes resource limits (spec.containers[].resources.limits.memory) to prevent a single process from exhausting system memory and causing a wider outage.
