# Apache Axis2/Java: unbounded request bodies let anyone exhaust memory or disk

Link for people: https://infrastack.ai/live/CVE-2026-123770 (this .md is for agents)

Apache Axis2/Java reads multipart and form-urlencoded request bodies with no size limit and leaves multipart temporary files behind. An unauthenticated caller can send large requests to exhaust server memory or disk.

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

## How to check

- Check the Axis2 version in your dependencies, for example `axis2-kernel` in `pom.xml` or the WAR's `WEB-INF/lib`.
- Confirm whether the service accepts multipart or form-urlencoded messages from the network.

## Fix

- Apache Axis2/Java: upgrade to `2.0.2` or later, which bounds these bodies with configurable limits and deletes temporary files.

## From the sources

Allocation of Resources Without Limits or Throttling vulnerability in Apache Axis2/Java. The multipart/form-data and application/x-www-form-urlencoded message builders read the request body directly from the transport stream with no size limit, so the servlet container's post-size limit did not apply, and multipart temporary files were not deleted. An unauthenticated caller could exhaust memory or disk. Version 2.0.2 bounds these bodies with configurable limits and deletes temporary files. This issue affects Apache Axis2/Java: through 2.0.1. Users are recommended to upgrade to version 2.0.2, which fixes the issue.
