  "title": "Improper package allowlist matching in vm2 NodeVM",
  "summary": "vm2 before 3.11.7 can let sandboxed NodeVM code evade an external-package allowlist by requesting a similarly named package. This can cause unauthorized package code to run in the host process when the application uses a custom resolver and that resolver can find a colliding package in an attacker-influenced location.",
  "mitigation": "Upgrade the npm vm2 package to version 3.11.7 or later. Until upgraded, do not use custom resolvers that search attacker-writable package locations, and restrict such resolver paths to trusted dependencies.",
