npm audit reports high severity vulnerabilities for marked and markdown-link-extractor dependencies:

$ npm audit
# npm audit report

  Depends on vulnerable versions of marked
  node_modules/markdown-link-extractor
    markdown-link-check  *
    Depends on vulnerable versions of markdown-link-extractor
    node_modules/markdown-link-check

3 high severity vulnerabilities

Some issues need review, and may require choosing
a different dependency.

markdown-link-check is my only dependency on this project:

  "devDependencies": {
    "markdown-link-check": "^3.9.0"
  },

npm audit fix cannot solve the issue.
