jsoup XmlTreeBuilder vulnerable to memory exhaustion through deeply nested namespace declarations

0.2.2 - 0.3.1
Summary
jsoup XmlTreeBuilder vulnerable to memory exhaustion through deeply nested namespace declarations
Details
jsoup through 1.23.2, fixed in commit 862ba2f, contains an uncontrolled resource consumption vulnerability in XmlTreeBuilder that allows remote attackers to exhaust JVM heap memory by supplying a deeply nested XML document with uniquely-namespaced elements. The builder copies the entire inherited namespace map on every start element, causing quadratic time and memory complexity, which attackers can exploit to trigger an OutOfMemoryError and terminate the application.
