| Título | java-json-tools json-patch 1.13 Stack Overflow DoS via Uncontrolled Recursion |
|---|
| Descrição | JsonMergePatch.fromJson() uses a recursive deserializer (JsonMergePatchDeserializer) that recurses without any depth limit. A deeply nested JSON object (2000+ levels) causes StackOverflowError, killing the processing thread. This is a separate code path from Jackson's own parsing — even if Jackson 2.15+ limits parsing depth to 1000, a programmatically-built JsonNode passed to JsonMergePatch.fromJson() still triggers the unguarded recursion. |
