How to Fix CVE-2026-57111

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

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

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-57111, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

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

Note: The mvn dependency:tree 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-1385: Missing Origin Validation in WebSockets, where the product uses a websocket, but it does not properly verify that the source of data or communication is valid. In Software, 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

Permissive Cross-Origin Resource Sharing (CORS) in the REST API (helix-rest, org.apache.helix.rest.server.filters.CORSFilter) in Apache Helix through 2.0.0 on all platforms allows a remote attacker controlling a web page visited by an authorized user to read responses from and issue cross-origin requests to administrative REST endpoints via a cross-origin request from an arbitrary origin, since the filter unconditionally returns Access-Control-Allow-Origin: * together with Access-Control-Allow-Credentials: true and reflects arbitrary Access-Control-Request-Method / Access-Control-Request-Headers values in preflight responses. Users are recommended to upgrade to version 2.0.1, which fixes this issue.
