  "title": "AggregateError sanitization bypass in vm2",
  "summary": "vm2 versions before 3.11.8 can fail to sanitize certain cyclic or repeatedly referenced host AggregateError objects passed into sandbox exception handling. A sandboxed attacker may escape the sandbox and access or execute actions with host-process privileges when an exposed host function throws a qualifying error that the sandbox catches.",
  "mitigation": "Upgrade the npm vm2 package to version 3.11.8 or later. Until upgraded, do not expose host functions to untrusted sandbox code if they can throw host-side AggregateError objects.",
