How to Fix CVE-2022-3916

To remediate this vulnerability, upgrade all affected Keycloak parent 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-parent fixed: 20.0.2
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-parent</artifactId>
    <version>20.0.2</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-2022-3916, 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 parent in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 20.0.2), 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-613: Insufficient Session Expiration, where according to wasc, "insufficient session expiration is when a web site permits an attacker to reuse old session credentials or session ids for authorization.". In Keycloak parent, 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

An issue was discovered in Keycloak when using a client with the `offline_access` scope. Reuse of session ids across root and user authentication sessions and a lack of root session validation enabled attackers to resolve a user session attached to a different previously authenticated user. This issue most affects users of shared computers. Suppose a user logs out of their account (without clearing their cookies) in a mobile app or similar client that includes the `offline_access` scope, and another user authenticates to the application. In that case, it will share the same root session id, and when utilizing the refresh token, they will be issued a token for the original user.
