Advisory Summary

CVE-2026-85301 is a MODERATE (CVSS 4.8) security vulnerability vulnerability (CWE-287: Improper Authentication) affecting Software libraries in the Maven ecosystem. The weakness occurs when when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-85301

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-2026-85301, 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. 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

Improper Authentication vulnerability in Apache Camel Keycloak component. This issue affects Apache Camel: from 4.15.0 before 4.18.5, from 4.19.0 before 4.22.1. The security processor validated the issuer of an introspected token only when the introspection response actually carried an iss claim. When the claim was absent the check was skipped rather than treated as a failure, so a token that the configured issuer did not mint could be accepted provided the introspection endpoint answered without naming an issuer. Reaching this requires an introspection endpoint that omits iss and accepts tokens from more than one issuer, which is not the default Keycloak arrangement, hence the low severity; where that arrangement exists the consequence is that the deployment authenticates a caller it should have rejected. 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. An absent iss claim is now treated as a validation failure rather than as a reason to skip the check. For deployments that cannot upgrade immediately, ensure the introspection endpoint returns the iss claim, and that it serves exactly one issuer.
