Detailsinfo

A vulnerability, which was classified as critical, was found in Apache TomEE up to 10.2.x/11.0.0-M1. This affects some unknown processing. The manipulation with an unknown input leads to a access control vulnerability. CWE is classifying the issue as CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

When MicroProfile JWT role-based access control is used, the access constraints of JAX-RS resources are not always enforced as declared: resources that declare an empty set of allowed roles are accessible to every caller, resource classes that inherit the same method from a common superclass share their constraints, and class-level constraints declared on a superclass are ignored. A remote attacker can invoke resources that should be denied to them, in some configurations without authentication. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
