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.

A vulnerability was found in kiali v1.30.0 when the authentication strategy OpenID is used. When RBAC is enabled, Kiali assumes that some of the token validation is handled by the underlying cluster. Hence, when OpenID implicit flow is used with RBAC turned off, this token validation doesn't occur and may allow a malicious user to bypass the authentication.

A content spoofing vulnerability was found in Kiali. It was discovered that Kiali does not implement error handling when the page or endpoint being accessed cannot be found. This issue allows an attacker to perform arbitrary text injection when an error response is retrieved from the URL being accessed.
