How to Fix CVE-2026-3190

To remediate this vulnerability, upgrade all affected Keycloak dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.keycloak:keycloak-server-spi-private fixed: 26.5.6 
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-server-spi-private</artifactId>
    <version>26.5.6</version>
</dependency>
org.keycloak:keycloak-services fixed: 26.5.6 
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-services</artifactId>
    <version>26.5.6</version>
</dependency>
org.keycloak:keycloak-model-jpa fixed: 26.5.6 
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-model-jpa</artifactId>
    <version>26.5.6</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.keycloak

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-3190, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.keycloak

Analyze the terminal output to locate any version of Keycloak in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 26.5.6), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.keycloak command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-280: Improper Handling of Insufficient Permissions or Privileges, where the product does not handle or incorrectly handles when it has insufficient privileges to access resources or functionality as specified by their permissions. this may cause it to follow unexpected code paths that may leave the product in an invalid state. In Keycloak, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A flaw was found in Keycloak. The User-Managed Access (UMA) 2.0 Protection API endpoint for permission tickets fails to enforce the `uma_protection` role check. This allows any authenticated user with a token issued for a resource server client, even without the `uma_protection` role, to enumerate all permission tickets in the system. This vulnerability partial leads to information disclosure.
