Summary

A flaw was found in the Admin REST API of Keycloak, an open-source identity and access management solution. The issue occurs because the API uses a per-request in-memory cache to resolve clients by their unique identifier without verifying if the client belongs to the realm specified in the request path. This allows an administrator with limited privileges to read or modify sensitive client configurations in the master realm by accessing them through a realm they control. Successful exploitation could lead to the exposure of client credentials or the redirection of administrative login attempts to malicious sites.
