  "title": "Regular expression denial of service in mammoth.js",
  "summary": "mammoth.js versions 1.3.0 through 1.12.2 are affected by a regular expression denial-of-service issue in style-map parsing.

Exploitation requires the application to process the attacker-controlled document with the affected component.",
