## Overview

A flaw was found in the client registration component of Keycloak, an open-source identity and access management solution. When a vault provider is used to store sensitive information, an authenticated client owner can use a specially crafted reference to trick the system into revealing secrets. By updating a client secret to point to a vault entry and then requesting the client configuration, the owner can see the secret value in plain text. This could lead to the exposure of sensitive credentials that the user should not be able to access.

## Affected

- `keycloak-services (all versions)`
- `rhbk/keycloak-rhel9 (all versions)`
- `keycloak-services`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.

### Workarounds

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
