CVE-2026-123753 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. 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. EPSS estimates a 0.22% chance of exploitation in the next 30 days.

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.
