An Information Exposure vulnerability was found in the GET /admin/realms/{realm}/authentication/config/{id} endpoint of Keycloak. The root cause is located in the ModelToRepresentation.toRepresentation method, which copies the configuration map without filtering or masking entries marked as secret in the provider metadata. Consequently, an authenticated user with the view-realm role can retrieve raw secret values, such as secret.key for reCAPTCHA and api.key for reCAPTCHA Enterprise. Additionally, these unmasked secrets are serialized into admin events, making them visible to any user with permission to read administrative logs. An attacker can use these secrets to undermine the integrity of bot-detection mechanisms in the affected realm.
