How to Fix GHSA-2rjv-cv85-xhgm

To remediate this vulnerability, upgrade all affected Opensearch security 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.opensearch.plugin:opensearch-security fixed: 2.19.3.0
<dependency>
    <groupId>org.opensearch.plugin</groupId>
    <artifactId>opensearch-security</artifactId>
    <version>2.19.3.0</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.opensearch.plugin

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-2rjv-cv85-xhgm, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.opensearch.plugin

Analyze the terminal output to locate any version of Opensearch security in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.19.3.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.opensearch.plugin 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Opensearch security, 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

### Impact OpenSearch versions 2.19.2 and earlier improperly apply Field Level Security (FLS) rules on fields which are not at the top level of the source document tree (i.e., which are members of a JSON object). If an FLS exclusion rule (like `~object`) is applied to an object valued attribute in a source document, the object is properly removed from the `_source` document in search and get results. However, any member attribute of that object remains available to search queries. This allows to reconstruct the original field contents using range queries. ### Patches The issue has been resolved in OpenSearch 3.0.0 and OpenSearch 2.19.3. ### Workarounds If FLS exclusion rules are used for object valued attributes (like `~object`), add an additional exclusion rule for the members of the object (like `~object.*`).
