CVE-2023-35110Public exploitNetwork attack vector

Service crash via recursive cyclic-object encoding

Published Jun 14, 2023 · Updated Jan 2, 2025

Stack exhaustion in jjson 0.1.7 and earlier allows attackers to crash a consuming Java service by submitting a crafted object. JSONAnnotationEncoder.encodeMap recursively re-encodes map values without detecting self-references or enforcing a depth limit, exhausting the Java call stack. The application must pass attacker-controlled cyclic or deeply nested object structures to the encoder; successful exploitation interrupts that service process.
