Technical description

Quarkus is a Cloud Native, (Linux) Container First framework for writing Java applications. In versions prior to 3.24.1, 3.20.2, and 3.15.6, there is a potential data leak when duplicating a duplicated context. Quarkus extensively uses the Vert.x duplicated context to implement context propagation. With the new semantic data from one transaction can leak to the data from another transaction. From a Vert.x point of view, this new semantic clarifies the behavior. A significant amount of data is stored in the duplicated context, including request scope, security details, and metadata. Duplicating a duplicated context is rather rare and is only done in a few places. This issue has been patched in version 3.24.1, 3.20.2, and 3.15.6.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
