# Apache Axis2/Java: unbounded JSON request bodies let callers exhaust server memory

Link for people: https://infrastack.ai/live/CVE-2026-120367 (this .md is for agents)

Apache Axis2/Java's JSON message builders (Gson, Moshi and HTTP/2 variants) read the whole request body into memory with no size limit. An unauthenticated caller can send a very large JSON request and exhaust the server's memory.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the Axis2/Java version in your dependencies, for example with `mvn dependency:tree | grep axis2` or by inspecting the WAR's lib directory.
- Confirm whether JSON services are exposed through the Gson, Moshi or HTTP/2 message builders.

## Fix

- Apache Axis2/Java: upgrade to `2.0.2`, which bounds JSON request bodies with the jsonMaxRequestSize parameter.

## From the sources

Allocation of Resources Without Limits or Throttling vulnerability in Apache Axis2/Java. The JSON message builders, including the Gson, Moshi and HTTP/2 variants, buffered the entire request body with no size limit, so an unauthenticated caller could exhaust server memory with a large JSON request. Version 2.0.2 bounds JSON request bodies with the configurable jsonMaxRequestSize parameter. This issue affects Apache Axis2/Java: through 2.0.1. Users are recommended to upgrade to version 2.0.2, which fixes the issue.
