Clusters using Calico (version 3.14.0 and below), Calico Enterprise (version 2.8.2 and below), may be vulnerable to information disclosure if IPv6 is enabled but unused. A compromised pod with sufficient privilege is able to reconfigure the node’s IPv6 interface due to the node accepting route advertisement by default, allowing the attacker to redirect full or partial network traffic from the node to the compromised pod.
The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
