Low risk43th percentile - higher than 43% of all known CVEs
Summary
Armeria, a microservice framework supported by Spring, had an issue with handling matrix variables in versions prior to 1.24.3. As a result, Armeria decorators might not be invoked, allowing an attacker to bypass authorization by sending a specially crafted request.
Risk Assessment
Organizations may be exposed to unauthorized access to resources, potentially leading to serious security breaches. Bypassing authorization could result in unauthorized operations being executed within the system.
Recommendation
It is recommended to upgrade to version 1.24.3 or later to patch this vulnerability. Additionally, conducting a security audit of applications using Armeria is advisable.

Original NVD description (English source)
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. Prior to version 1.24.3, the Armeria decorators might not invoked because of the matrix variables. If an attacker sends a specially crafted request, the request may bypass the authorizer. Version 1.24.3 contains a patch for this issue.
