Overview
rexml is an An XML toolkit for Ruby.

Affected versions of this package are vulnerable to Improper Restriction of XML External Entity Reference ('XXE') via tree parser APIs like REXML::Document.new function. An attacker can cause the application to consume excessive resources by submitting specially crafted XML documents with many deep elements that have the same local name attributes.

Note:

This is only exploitable if a tree parser API is used to parse untrusted XMLs.
