DescriptionGitHub Advisory

Impact

Mermaid v11.14.0 and earlier are vulnerable to a denial-of-service attack when rendering gantt charts, if they use the excludes attribute to exclude all dates.

Example:

gantt
  excludes monday,tuesday,wednesday,thursday,friday,saturday,sunday
  DoS :2025-01-01, 1d

mermaid.parse is unaffected, unless you then call the ganttDb.getTasks() (which is called when rendering a diagram).
