CVE-2022-45685Public exploitNetwork attack vector

Service interruption via unbounded JSON recursion

Published Dec 13, 2022 · Updated Apr 22, 2025

Stack overflow in Jettison before 1.5.2 allows remote attackers to interrupt applications that parse crafted JSON data. JSONTokener recursively constructs JSONObject or JSONArray instances for each nested opening brace without enforcing a recursion-depth limit. Exploitation requires an application to pass attacker-controlled JSON to Jettison; excessive nesting raises a StackOverflowError and interrupts the calling application's service.
