  "title": "Nested-brace stack exhaustion in brace-expansion",
  "summary": "brace-expansion versions before 1.1.20, 2.1.6, 3.0.8, and 5.0.11 can consume the Node.js call stack when expanding deeply nested brace patterns. An attacker may terminate a process that expands attacker-controlled patterns directly or through consumers such as minimatch or glob; exposure requires untrusted glob or brace-expansion input.",
  "mitigation": "Upgrade brace-expansion to 1.1.20, 2.1.6, 3.0.8, 5.0.11, or a later compatible release. Until updated, reject or limit deeply nested brace syntax in untrusted patterns before expansion.",
