As written in the advisory (Markdown source, shown as plain text).

A flaw was found in Keycloak before 13.0.0, where it is possible to force the server to call out an unverified URL using the OIDC parameter `request_uri`. This flaw allows an attacker to use this parameter to execute a Server-side request forgery (SSRF) attack.
