Kerentanan Server-Side Request Forgery (SSRF) pada redhat build of keycloak, redhat jboss enterprise application platform +2 lainnya. Skor CVSS 3.1 3.1 (Low) menurut NVD.

Deskripsi (NVD)

A flaw was found in Keycloak. An authenticated attacker can perform Server-Side Request Forgery (SSRF) by manipulating the `client_session_host` parameter during refresh token requests. This occurs when a Keycloak client is configured to use the `backchannel.logout.url` with the `application.session.host` placeholder. Successful exploitation allows the attacker to make HTTP requests from the Keycloak server’s network context, potentially probing internal networks or internal APIs, leading to information disclosure.
