It enables the user to generate consistent, usable documentation that can be exported to a number of formats very easily, and also supports extending for custom Ruby constructs such as custom class level definitions.
Security Fix(es):
YARD is a Ruby Documentation tool. Prior to version 0.9.42, a path traversal vulnerability was discovered in YARD when using yard server to serve documentation.
