Armeria is a microservice framework Spring supports Matrix variables. When Spring integration is used, Armeria calls Spring controllers via `TomcatService` or `JettyService` with the path that may contain matrix variables. In the package com.linecorp.armeria:armeria versions prior to 1.24.3, the Armeria decorators might not be invoked because of the matrix variables. If an attacker sends a specially crafted request, the request may bypass the authorizer.
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.
