  "title": "node-marked: Marked is a markdown parser and compiler",
  "description": "Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression \u0060block.def\u0060 may cause catastrophic backtracking against some strings and lead to a regular expression denial of service (ReDoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources.",
