A flaw was found in Quarkus versions prior to 2.7.1.Final. The state and potentially associated permissions can leak from one web request to another in RestEasy Reactive. This flaw allows a low-privileged user to perform operations on the database with a different set of privileges than intended.
CWE-863 - Incorrect Authorization
Authorization is a security mechanism performed by an application to grant or deny access to the requested resources by verifying the privileges of the user. When an application lacks effective authorization mechanisms, it enables unauthorized users to gain unintended privileges and illegitimate access to resources. Such a vulnerability may result in exposure of sensitive information, denial of service, arbitrary code execution, and complete system takeover.
