8.5.5.12, 9.0 prior to 9.0.0.4, or Liberty 17.0 prior to 17.0.0.2. It

require multiple steps, explicit confirmation, or a unique token when
performing certain sensitive actions. An unauthenticated, remote
attacker can exploit this vulnerability, by convincing a user to
follow a specially crafted link, to perform unintended actions.");
