Advisory Summary

CVE-2026-85245 is a MODERATE (CVSS 5.9) security vulnerability vulnerability (CWE-488: Exposure of Data Element to Wrong Session) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not sufficiently enforce boundaries between the states of different sessions, causing data to be provided to, or used by, the wrong session.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-85245

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-2026-85245, 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-488: Exposure of Data Element to Wrong Session, where the product does not sufficiently enforce boundaries between the states of different sessions, causing data to be provided to, or used by, the wrong session. 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

Exposure of Data Element to Wrong Session vulnerability in Apache Camel Thrift component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Thrift data format unmarshalled incoming data into the shared defaultInstance of the target type rather than into a fresh copy, and returned that shared object as the exchange body. Because the instance is shared process-wide, state written while unmarshalling one message stayed on the object and was visible to every later message that used the same type. Fields absent from a later payload retained the previous message's values, so content belonging to one sender could be read while processing another sender's message, and concurrent exchanges could observe each other's partially written state. In a deployment that serves more than one tenant or user through the same route, that is disclosure of one party's data to another. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. Unmarshalling now deserializes into a copy, so each exchange gets its own instance and no state carries between messages. For deployments that cannot upgrade immediately, copy the unmarshalled body into a new instance immediately after the data format runs, and do not retain references to the returned object.
