Twisted: Unauthenticated Remote Denial of Service in the Twisted words domish XML Element Stream via an Unbounded Element Tree

A flaw was found in Twisted. An unauthenticated remote attacker can cause a Denial of Service (DoS) by exhausting server memory. The issue occurs because the XML stream parser retains unfinished elements in memory without enforcing size or element count limits. By transmitting a continuous stream of child elements within an unclosed container during pre-authentication communication, an attacker can crash the server process.
