CVE-2026-123753 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It affects Apache Axis2/Java; fixed in 2.0.2.

## Summary

Apache Axis2/Java is affected by a server-side request forgery flaw in how it handles WS-Addressing ReplyTo and FaultTo endpoints. An attacker can make the server connect to internal hosts or send response content to a host of their choosing.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- org.apache.axis2:axis2-kernel (Maven): fixed in 2.0.2
  - Fixed in 2.0.2 (released Oct 29, 2026, 11 days before disclosure).
  - The latest release, 2.0.2, is not affected.

## Description

Server-Side Request Forgery (SSRF) vulnerability in Apache Axis2/Java. An unauthenticated caller could supply a non-anonymous WS-Addressing wsa:ReplyTo or wsa:FaultTo address, and Axis2 would open a connection to that address to deliver the response or fault, allowing requests to internal hosts and delivery of response content to a host of the caller's choosing. From 2.0.2, decoupled responses are refused unless allowNonAnonymousResponseEndpoints is enabled, and enabled endpoints are restricted by scheme and screened at both the header-parsing and transport-selection layers. This issue affects Apache Axis2/Java: through 2.0.1. Users are recommended to upgrade to version 2.0.2, which fixes the issue.
