How to fix?

There is no fixed version for RHEL:10 openshift-kube-controller-manager.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift-kube-controller-manager package and not the openshift-kube-controller-manager package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

grpc-gateway v2.28.0 is vulnerable to Incorrect Access Control. The application processes the X-HTTP-Method-Override header in ServeMux.ServeHTTP without restricting allowed methods. When a POST request with Content-Type application/x-www-form-urlencoded includes this header, the request method is rewritten to an arbitrary attacker-supplied value before routing. This allows bypassing method-based access controls enforced by upstream proxies or WAFs.
