Advisory Summary

CVE-2026-97404 is a CRITICAL security vulnerability vulnerability (CWE-348: Use of Less Trusted Source) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product has two different sources of the same data or information, but it uses the source that has less support for verification, is less trusted, or is less resistant to attack.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-97404

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-2026-97404, 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-348: Use of Less Trusted Source, where the product has two different sources of the same data or information, but it uses the source that has less support for verification, is less trusted, or is less resistant to attack. 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

In OpenStack Zaqar before 22.0.2, WSGI transport mishandles the URL-Signature header. By sending a request with an empty URL-Signature header, an unauthenticated remote attacker who knows a target project's UUID may bypass both Keystone authentication and pre-signed URL verification, resulting in the ability to read, enumerate, create, and delete that project's queues, messages, claims, and subscriptions. By additionally claiming an administrative role, the attacker may also perform administrative operations, such as managing pools and flavors in admin_mode deployments. Only deployments using the WSGI transport with an authentication strategy configured are affected; the websocket transport is not affected.
