An insufficient JWT validation vulnerability was found in Kiali versions 0.4.0 to 1.15.0 and was fixed in Kiali version 1.15.1, wherein a remote attacker could abuse this flaw by stealing a valid JWT cookie and using that to spoof a user session, possibly gaining privileges to view and alter the Istio configuration.
