  "title": "Quadratic denial of service in npm toml parsing",
  "summary": "The npm `toml` package before 5.0.1 can perform excessive synchronous work while parsing TOML documents with many array-of-tables headers. An attacker who can cause an application to parse a supplied TOML document may block the Node.js event loop and disrupt service.",
  "mitigation": "Upgrade the npm `toml` package to version 5.0.1 or later. Until upgraded, restrict untrusted TOML input and enforce limits on document size and table counts before parsing.",
