CVE-2022-40152Public exploitNetwork attack vector

Application crash via unbounded DTD subset recursion

Published Sep 16, 2022 · Updated Apr 21, 2025

Denial of service in FasterXML Woodstox before 5.4.0 and 6.0.0 through 6.3.1 allows attackers to crash XML-processing applications. FullDTDReader recursively parses nested declarations in an enabled DTD subset without enforcing a depth limit, exhausting the Java thread stack. Exposure requires DTD processing and attacker-controlled XML; the resulting StackOverflowError interrupts the hosting application.
