Consul Community Edition and Consul Enterprise 1.20.1 through 2.0.2 are vulnerable to an L7 intention authorization bypass when a service proxy is configured with a custom public listener.
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
