CVE-2023-34614Public exploitNetwork attack vector

Application crash via cyclic-object stack exhaustion

Published Jun 14, 2023 · Updated Jan 6, 2025

Denial of service in jmarsden jsonij 0.5.2 and earlier allows remote attackers to crash consuming applications via cyclic objects. Its object-graph traversal follows repeated cyclic references without terminating, causing recursive processing to exhaust the Java call stack. Exploitation requires an application to pass attacker-influenced object graphs to the library; the documented consequence is application unavailability, with no established data compromise.
