  "title": "Unauthenticated denial of service in body-parser decompression",
  "summary": "Applications using body-parser with its default handling of compressed request bodies are affected. An unauthenticated attacker can cause the application process to terminate by sending a malformed encoded request; parsing occurs before route selection, so no matching endpoint is required.",
  "mitigation": "Upgrade body-parser to version 2.4.0 or 1.20.9. If compressed request bodies are not needed, configure the middleware with `inflate: false` to reject them.",
