3DescriptionCVE.org
A flaw has been found in java-json-tools json-patch up to 1.13. Affected is the function JsonMergePatch.fromJson of the file JsonMergePatchDeserializer.java. Executing a manipulation can lead to stack-based buffer overflow. The attack may be performed from remote. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Stack exhaustion in java-json-tools json-patch ≤1.13 enables remote unauthenticated denial of service by submitting a crafted deeply-nested JSON Merge Patch document to any application endpoint that invokes JsonMergePatch.fromJson. The vulnerability triggers an uncontrolled recursive deserialization path in JsonMergePatchDeserializer.java, causing JVM thread stack exhaustion. …
