CVE-2025-11538: 
Java vulnerability analysis and mitigation

Overview

A vulnerability (CVE-2025-11538) was discovered in Keycloak's server distribution where enabling debug mode (--debug ) insecurely defaults to binding the Java Debug Wire Protocol (JDWP) port to all network interfaces (0.0.0.0). The vulnerability was disclosed on November 13, 2025, affecting Keycloak versions up to and including 26.4.4 (NVD, Red Hat).

Technical details

The vulnerability is classified as CWE-1327 (Binding to an Unrestricted IP Address) with a CVSS v3.1 Base Score of 6.8 (Medium) and vector string CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N. The issue occurs when debug mode is enabled, which exposes the JDWP port to the local network, potentially allowing attackers on the same network segment to attach a remote debugger (NVD, Miggo).

Impact

The vulnerability allows an attacker on the same network segment to attach a remote debugger and achieve remote code execution within the Keycloak Java virtual machine, potentially compromising the confidentiality and integrity of the system (NVD).

Mitigation and workarounds

Red Hat has released security updates addressing this vulnerability in Keycloak 26.4.4. Users are advised to back up their existing installation, including all applications, configuration files, databases, and database settings before applying the update (Red Hat Advisory).
