Advisory Summary

CVE-2026-82433 is a MODERATE (CVSS 6.5) security vulnerability vulnerability (CWE-522: Insufficiently Protected Credentials) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-82433

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-2026-82433, 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-522: Insufficiently Protected Credentials, where the product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. 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

Description `getNimbusConf` returned the complete daemon configuration without redaction after only a user-level authorization check. Where the cluster is configured with them, that response includes `storm.zookeeper.auth.payload` and the keystore and truststore passwords for the Thrift, Netty and ZooKeeper TLS configuration. The project masks passwords elsewhere before display, so the omission here is inconsistent rather than intended. The UI endpoint `/api/v1/cluster/configuration` compounded this. It carried no `@AuthNimbusOp` annotation, and the authorization filter treated a missing annotation as "no gate required" and returned immediately, so the endpoint applied no per-user check at all and proxied the request under the UI daemon's own principal. Any user able to pass `ui.filter` therefore received the full configuration, including principals that Nimbus itself would have refused.  Mitigation Upgrade to 3.1.0, where credential-bearing values are masked before the configuration is served and where every UI API endpoint must declare its authorization explicitly. Users who cannot upgrade immediately should place the UI behind an authenticating reverse proxy that restricts `/api/v1/cluster/configuration`, and should rotate the ZooKeeper authentication payload and any TLS keystore or truststore passwords that were reachable through it.
